How can you make multi-line axis labels with TeX not left-justified in R2026a?
I just started using R2026a and encountered a problem with axis labels. In R2025b on a different computer, I don’t have this problem. Multi-line labels that have TeX in them render left justified, .e.g.
xlabel( sprintf( ‘normaln\bfbold’ ) )
whereas those with no TeX render centered as expected
ylabel( sprintf( ‘normalnbold’ ) )
Setting the ‘HorizontalAlignment’ property of the label to ‘center’ after the fact, as suggested by a web search does not fix the problem. I get the same behavior creating a text object with text() as opposed to xlabel(), and can’t think of a workaround other than creating a separate text object for each line, which would make be abandon R2026a for the time being.

How can I dynamically create and configure a subclass of an abstract class from a file or script in one step in MATLAB?
In MATLAB, I have an abstract class called "Vehicle" and concrete subclasses like "Car" and "Bike". In my "Garage" class, the "vehicle" property is set dynamically at runtime by reading a config script (e.g., "garageConfig.m"). Right now, I use a variable "vehicleType" in "garageConfig.m" to determine which subclass to instantiate. But the problem is I have to:Run "garageConfig.m" to get the value for "vehicleType", then set the property "vehicle" to the correct child (e.g., obj.vehicle = Bike()).Then run "garageConfig.m" again to populate the property values (like "vehicle.color", "vehicle.wheels", etc.) for the instantiated child class.
Is there a better way to do this, so I don’t have to run the config script twice to set up the "vehicle" object and its properties?

How to access to i2c Qwiic connector on Arduino Uno R4Wifi?
I am using an Arduino UnoR4Wifi to read i2c accelerometer (LiS3DH) in Matlab and Simulink. This works ok using i2c Bus 0, with the accelerometer wires individually plugged into the board (A4,A5,3.3v,Gr). But I want to use the in-built ‘Qwiic’ connector on the Arduino board (aka ‘StemmaQT’ connector) for convenient plug-and-play access so I can quickly attach/detach sensors during an experiment.
However, when i attach the accelerometer to the Qwiic connector (Bus 1) it is not recognised by Matlab. I have tried using pull-down resistors attached to the SDA/SCL connections to activate Bus 1, to no avail. I am not sure if this is a Matlab software limitation, or an Arduino hardware limitation. Matlab suggests Bus 1 is not valid (see code below with no accelerometer attached), so i am guessing it might be a software limitation.
Any advice appreciated!

Entra and Microsoft 365 Could Improve License Reporting
Entra ID and Microsoft 365 Offer Different License Insights
On April 22, the Entra ID team announced the availability of License Usage Insights, new information presented in the Entra admin center to help tenants “track adoption of core identity protections and uncover potential gaps in your security coverage.” After the motherhood and apple pie of the marketing prouncement, we learn that license usage insights are also intended to help tenants understand when they need more Entra premium licenses.
The Microsoft 365 admin center has a new dashboard view. One of the cards reveals license information. It would be nice if Microsoft took a consistent and effective approach to reporting license details, but they don’t. Let’s look at what happens.
Entra License Insights
The Entra team is very big into delivering insights, and the license usage insights follow on from the preview of group insights delivered recently. It’s good that Microsoft goes to the effort of generating insights for tenants. Figure 1 shows the data for my (small) tenant, accessed through the Licenses section of the Entra admin center.
The first insight shows that the tenant has ten Entra P1 and ten Entra P2 licenses. These licenses are both included in Microsoft 365 E5. The right-hand side graph tracks usage patterns over the last six months and reports a peak of 12 users of conditional access policies. Some of the users without Microsoft 365 E5 have obviously used conditional access. According to this data, I “owe” Microsoft for two Entra P1 licenses.
The graph has a section for guest users, who might be forced to use conditional access to access the tenant. Guest accounts should be licensed on a monthly active user basis (MAU), and Microsoft makes the first 50,000 MAU free of charge.
The left-hand graphic offers a feature usage report. I learned here that 1 license was being used for risk-based conditional access, but without the ability to click-through to see the details of the account, the insight leaves it to the tenant to find out who this might be. The lack of an option to download details behind the insights is also regrettable.
Reporting Licenses in Microsoft 365
It’s reasonable that the Entra admin center should only report insights for Entra licenses. The new dashboard card for licenses in the Microsoft 365 admin center focuses on Microsoft 365 licenses but offers some odd results. As you can see from Figure 2, the card says that my tenant has 61 users. That’s just plain wrong. It seems like the figure includes the unlicensed user accounts created for purposes like Exchange Online shared and room mailboxes and accounts synchronized from other tenants in a multi-tenant organization.
Entra ID only supports user and guest accounts. It offers no way to identify utility accounts or accounts synchronized into a tenant that are licensed in another tenant. This flaw has been highlighted to Microsoft many times, but they have chosen not to introduce additional granularity for accounts.
The card also reports that 20 Microsoft 365 licenses are available but ignores other common licenses used by the tenant such as Office 365 E3. In fact, I don’t know how the admin center comes up with 20 Microsoft 365 licenses because only ten Microsoft 365 E5 licenses are available. Even adding the five Office 365 E5 licenses to the ten Microsoft 365 E5 licenses doesn’t result in 20.
License Management is a Well-Worn Road
It’s disappointing to see that information presented by the Microsoft 365 admin center is so obviously wrong. The Graph APIs for licenses are not an unknown secret (anyone can use the APIs to produce their own reports) and many people have created comprehensive license reporting scripts.
It would be nice if the Entra and Microsoft 365 admin teams took notice of what’s been done in the real world to generate valuable insights rather than the simplistic views they currently present.

How to find a function in the path – securely?
What is a safe method to check, where a specific function exists in Matlab’s path? It should not matter, if the function is an M, P or MEX file.
Actually, this is a job for which() . To avoid collisions with local variables, it should be hidden in a function:
function Reply = safeWhich(varargin)
Reply = which(varargin{:});
end
This fails for ‘varargin’, as expected:
safeWhich(‘varargin’)
But there are further traps
safeWhich(‘R’) % Same for ‘P’
In Matlab R2018b under Windows I get:

function Reply = safeWhich_2(varargin)
Reply = which(varargin{:});
Reply = cellstr(Reply);
Reply = Reply(isfile(Reply)); % Worked in R2018b, no effect in R2025a
end
safeWhich_2(‘R’)
The exist() command does have the power to find functions properly, but it does not reveal where.
The old function depfun() was replaced by the ugly matlab.codetools.requiredFilesAndProducts(). I could search in the corresponding code, couldn’t I? This function uses the code find here internally: "toolboxmatlabdepfun+matlab+depfun+internal+whichcallWhich.m". Here I find 91 functions and 11.3 MB of code. One function looks like this:
% 10^(-18) is effective zero in terms of possibility, which requries

function klno6phn_9faskf_na = callWhich(asm_foyan_knaouie8)

end
Obviously MathWorks struggles with comparable problems.

High Volume Email is Generally Available and Ready to Charge
Pricing for HVE Announced Effective June 1, 2026
In March 2026, Microsoft announced that general availability of the Exchange Online High-Volume Email (HVE) solution was imminent. On April 1, 2026, HVE duly attained general availability in a Technical Community post that revealed details of pricing amongst other things.
Paying to Send to Internal Recipients
The headline rate for HVE is $42 (U.S.) per one million email recipients, or $0.000042 per recipient. All recipients are internal because HVE doesn’t support sending email outside the tenant.
At first glance, the pricing is much lower than Azure Email Communication Service (ECS), which quotes $274 to send one million messages to external recipients. However, this is not an apple-to-apple comparison because one charges on a per-recipient basis while the other charges on a per-message basis. It’s entirely possible that each message will have a single recipient, but that’s not always the case.
ECS cites an average email size of 0.2 MB for the estimate cited above. The larger the message, the more you’ll pay. Increasing the size to 1 MB moves the dial to $370 according to the Azure price calculator. By comparison, HVE sets an upper limit of 10 MB per message.
Sending email with ECS isn’t difficult (here’s an example of using ECS to send an Outlook newsletter), if you have a moderate acquaintance with PowerShell. ECS comes with features that HVE doesn’t have, such as tracking message delivery. You can argue that this kind of feature isn’t necessary for an internally-facing email service because tools like message tracing for internal recipients are available out-of-the-box.
Configure a Billing Policy
After June 1, 2026, Microsoft will charge for HVE on a pay as you go (PAYG) basis through a credit card attached to an Azure subscription. To make sure that you can keep on using HVE after Microsoft enables charging, you’ll need to create a billing policy through the Pay as you go option under Billing in the Microsoft 365 admin center. Creating a billing policy essentially links a valid (active) Azure subscription with a PAYG service. During setup, you should create a new Azure resource group for HVE processing (Figure 1) because this will make Azure billing easier to understand. You can choose an existing resource group if you wish.
During setup, you get a chance to set a budget for the billing policy. This is to make sure that the PAYG service doesn’t exceed the expected level of cost during the monthly billing period. You can configure a mail-enabled security group to receive notifications when a budget percentage threshold is reached (Figure 2).
The final step is to assign the billing policy to the HVE service (Figure 3). Once connected, HVE will be ready to meter processing and generate charges to the credit card connected through the policy when Microsoft enables billing for HVE on June 1, 2026.
Billing Policy Management via PowerShell
PowerShell cmdlets are available to view and manage billing policies (see the Microsoft documentation for managing HVE). I don’t imagine that many will use PowerShell to manage billing policies because the admin UX works well, but here’s an example of running the Get-BillingPolicy cmdlet to view the details of the policy created above.
Get-BillingPolicy -ResourceType HVE
Id : c3601166-04c3-407b-9cf9-af7a5fa70bfe
FriendlyName : HVE Email Policy
IdentityType : Tenant
IdentityId : a662313f-14fc-43a2-9a7a-d2e27f4f3478

CreateDate : 21/04/2026 20:48:53
LastModifiedDate : 21/04/2026 20:50:42
What’s interesting here is that the resource provider name is Microsoft.Syntex, usually something that’s associated with SharePoint Online. This is likely explained by Exchange Online adopting the same PAYG billing mechanism as used by SharePoint services such as document translation.
All the cmdlets are in the Exchange Online management PowerShell module.
Setting a Reply-to Address for HVE Accounts
One thing that you will want to do with PowerShell is create a reply-to address for HVE accounts. This is a recent improvement to eliminate the problem of how to handle responses to HVE messages. Until recently, if a recipient replied to a message, the response when into a black hole because HVE accounts don’t have mailboxes. By configuring the accounts with a reply-to address, Exchange Online can redirect messages to a “real” address. This code shows what I did to find all HVE accounts in the tenant and set the same address (for a shared mailbox) for each.
[array]$HVEAccounts = Get-MailUser -HVEAccount
ForEach ($Account in $HVEAccounts) {
Set-HVEAccountSettings -Identity $Account.WindowsEmailAddress -ReplyTo "cServices@office365itpros.com"
}
Two Bulk Email Solutions When One Will Do
Now that HVE is generally available, Microsoft 365 tenants have a choice of two email platforms for bulk email (well, hybrid tenants can continue using Exchange Server and forget about the cloud platforms). Both HVE and ECS are built on Exchange Online. Both charge to send email. Wouldn’t it make a heap of sense to create just one bulk email platform that can handle both internal and external traffic? And while creating a unified bulk email platform, make sure that it’s much easier to use than either solution is today, especially for hardware devices like printers.
Organizational politics within Microsoft and available budgets might get in the way of creating a single unified bulk email platform built on Exchange Online, but it’s the right long-term direction.

Accelerating Frontier Transformation with Microsoft partners
AI has moved quickly from experimentation to production. Customers want measurable business outcomes, along with security, governance and responsible AI built in from day one. Microsoft partners are a meaningful differentiator to deliver these objectives. They turn ideas into deployable solutions by prioritizing the highest value use cases, building the right data and security foundations and establishing adoption and measurement capabilities so customers can run AI reliably in production.
Frontier Transformation is where AI becomes a repeatable, governed capability embedded into the flow of work, business processes and customer engagement. Customers are quickly moving from targeted pilots to operating AI at scale with a foundation built upon identity, data protection, compliance, monitoring and change management. As organizations expand from custom agents to agent-led processes, unified governance is essential so leaders can manage risk, track performance and scale with confidence.
Two essentials: Intelligence and Trust
Frontier Transformation depends on two essential elements: intelligence and trust. Customers want solutions grounded in their unique work intelligence, including their data, business context and operational realities. They also expect trust by design, with AI artifacts observable, managed and secured across the technology stack so they can deploy responsibly and scale with confidence.
A success framework for Frontier Transformation
Microsoft has developed a powerful framework for success as partners enable AI transformation for customers across all segments, industries and geographies:
- Enriching employee experiences: enabling businesses to empower employees with world-class tools and capabilities to activate a thriving, productive workforce
- Reinventing customer engagement: applying AI and agentic solutions to break through with customers, accelerate revenue growth, become more efficient at customer acquisition and deliver more personalized solutions
- Reshaping business processes: redesigning workflows across the business, enhanced by AI and agentic capability
- Bending the curve on innovation: AI acceleration is a powerful catalyst for business transformation and for addressing society’s biggest challenges — curing disease, addressing climate change and famine and other meaningful advancements
The “what” matters, and so does the “how.” Organizations that scale successfully put AI where people already work, enable innovation close to the business challenge and build observability at every layer so leaders can measure quality, govern risk and manage AI like a production system.
More than 90% of the Fortune 500 use Microsoft 365 Copilot, reflecting how quickly AI is becoming part of everyday work.(1) IDC predicts 1.3 billion agents in circulation by 2028(2) and 80% of the Fortune 500 are already using Microsoft agents, led by operationally complex industries like manufacturing, financial services and retail.(3) As customers move from piloting AI to agents embedded in their flow of work, governance and security need to scale with them.
Microsoft’s approach is straightforward: Copilot drives action in the flow of work, agents orchestrate workflows across systems and Microsoft Agent 365 provides a unified control plane designed to govern and secure agents at scale, with the same tools businesses use for employee administration, such as Microsoft admin center, Defender, Entra and Purview.
Partners are creating impact right now in three areas. First, agentic workflows that remove operational friction and orchestrate end-to-end work across operations, finance, supply chain and service. Second, Customer Zero maturity. Partners who adopt Copilot and agents internally build credibility and move faster because they have meaningful, real-world experiences that they translate into their go-to-market plans. Third, security as the foundation. There is no AI at scale without secure identity, protected data and strong governance.
Microsoft 365 E7 and Agent 365: The Frontier Suite
In March, Microsoft introduced Wave 3 of Microsoft 365 Copilot and announced Microsoft 365 E7: The Frontier Suite, with general availability of Microsoft 365 E7 and Microsoft Agent 365 on May 1, 2026.
Microsoft 365 E7 brings together Microsoft 365 E5 for secure productivity, Entra Suite for identity and access control, Microsoft 365 Copilot for AI in the flow of work and Agent 365 as the control plane to govern and scale agents. It is grounded in shared intelligence from Work IQ, the layer that brings together signals from the Microsoft 365 environment, including content, context and activity, so AI can operate with the right business grounding and policy awareness.
Microsoft Agent 365 provides a unified control plane for agents, enabling IT, security and business teams to observe, govern and secure agents across the organization. This applies to any agents an organization uses, whether they are built on Microsoft AI platforms, delivered by ecosystem partners or introduced through other technology stacks. It also applies the same security and compliance capabilities teams already rely on, including Microsoft Defender, Microsoft Entra and Microsoft Purview.
Some customer scenarios require custom agents. Microsoft Agent Factory is designed to accelerate the move from experimentation to execution. The Microsoft Agent Factory Pre-purchase Plan (P3) adds licensing flexibility across Copilot Studio, Microsoft Foundry, Fabric and GitHub, with tiered discounts intended to support broader adoption rather than isolated pilots. It also enables inclusion of tailored, role-based skilling at no additional cost to the customer, reducing adoption friction and increasing delivered value.
The opportunity for partners is end-to-end, and this is where the partner’s strategy really matters. Shifting from transaction-first to outcome-first, partners who iterate quickly, establish clear guardrails and build an operating rhythm for adoption move customers from interest to impact.
Over time, every organization will employ people who can direct and govern agents as part of daily work. Partners can make that capability real through packaged offers, change management and managed operations. Publishing those packaged offers in the Microsoft Marketplace adds a scalable route to market, improving discoverability and enabling a more repeatable buy-and-deploy motion as customers expand agent usage.
Partner success: What governed scale looks like in practice
“AI is at the forefront of everything we do. Through our ‘learn, use, create’ methodology and our AI Academy, we really support partners with learning paths.”
— Nicole Clark, Global Alliance Manager, Arrow Electronics
Partners are embracing Frontier Transformation by modernizing foundations, driving adoption, designing security into delivery and building agents that automate repeatable work and orchestrate business processes.
- Cognizant treated legacy automation as a platform modernization effort. Using Microsoft Power Platform, Copilot agents and governance frameworks, Cognizant migrated and modernized automation and scaled it across teams, consolidating platforms, lowering costs and reducing manual work through agent-led workflows.
- EPAM’s work with their customer Albert Heijn demonstrates what agent-first execution looks like in frontline scenarios. By delivering an employee-facing virtual assistant inside the retailer’s staff app, EPAM supported scenarios like restocking, onboarding and faster access to product and inventory information, with enterprise governance and observability in mind.
- Insight’s Flight Academy shows what it looks like to treat adoption as a program, not an announcement. Through a structured approach, Insight enables teams to build AI fluency in daily work and reinforces usage with practical learning and internal momentum that can scale beyond early enthusiasts.
- aCloud demonstrated a repeatable security pattern with their customer Jurong Engineering Limited (JEL) by bringing together Microsoft Purview, Microsoft Sentinel, Microsoft Defender XDR and Microsoft Security Copilot, paired with co-design workshops and cross-team alignment to strengthen compliance readiness.
- Arrow Electronics showed how distributor-led enablement can accelerate partner execution by using ArrowSphere to streamline Cloud Solution Provider (CSP) lifecycle management and ArrowSphere Assistant to surface AI-driven insights for renewals, upsell opportunities and Copilot adoption, complemented by a security dashboard that strengthens posture visibility and supports trust-by-design conversations.

This same disciplined approach is especially relevant in the small and medium business space (SMB), where Microsoft partners offer end-to-end capability through managed services offerings and solutions packaged into repeatable motions, tailored to this customer segment.
SMB momentum: Scaling work with Copilots and agents
As Microsoft 365 Copilot Business expands AI built for work to organizations with fewer than 300 users, SMBs have a practical path to adopt AI more broadly. CSP partners are well positioned to guide that journey with a motion that combines adoption, security and ongoing management.
New Omdia research illustrates that CSP is a durable growth model for partners. In a study of 267 CSP partners across 36 countries, 79% rated CSP authorization as good, very good or excellent, and 88% would recommend it to other partners.(4) Omdia also found that 60% of CSP partner revenue is now tied to value-added services, with licensing acting as the entry point to broader, services-led engagements.(6)
“We’re bringing customers resources that only a partner can deliver to them: our relationship with Microsoft, technical training and programs that push them further and faster to learn technologies like Microsoft Copilot Studio, Foundry and Fabric.”
— Chance Weaver, Global VP of AI Adoption, Pax8
SMB demand is also expanding. For CSP partners, the near-term opportunity is to standardize advancing Copilot and agents from conversation to consumption. Lead with a simple, repeatable motion: outcome selection, security baseline, deployment, adoption and optimization cadence. Renewal moments are often the easiest time to introduce change when paired with a clear business case and time-bound offers.
A simple, scalable approach is to roll out in stages:
- Deploy Microsoft 365 Copilot Business broadly, paired with a strong foundation of identity, data protection and compliance.
- Target high-propensity accounts with tools such as Microsoft CloudAscent and the AI Business Solutions & Security Insights dashboard to deepen adoption and standardize responsible prompting.
- Extend with agents to take on repeatable tasks and support key business processes, with governance and security built in.
Microsoft provides CSP partners with a powerful set of tools to combine licensing, lifecycle management and optimization into one customer relationship. Omdia notes that partners value operational advantages such as monthly billing flexibility and managing licenses through Partner Center for real-time provisioning and 24/7 license management. Partners can review the CSP incentives guide to understand the latest CSP incentives and how they map to an SMB motion.
Microsoft supports SMB-focused partners by combining product, security and go-to-market resources that make it easy to deliver a repeatable motion. That includes tools to assess readiness, prioritize the right use cases and track adoption over time, plus role-based skilling to build sales and technical and delivery confidence across Copilot, security and agents. For partners building managed services offerings, Microsoft Marketplace also provides a scalable route to market, improving discoverability and enabling customers to buy through familiar procurement paths, while Partner Center brings licensing and lifecycle management into the same operational flow.
Program momentum and updates
The Microsoft AI Cloud Partner Program continues to be the primary way we invest in partners as they build, sell and deliver cloud and AI solutions. Our focus is simple: enable partners to build capability, accelerate demand, differentiate in the market and scale repeatable delivery.
In February 2026, Microsoft introduced a wealth of expanded benefits updates across Copilot, security, Azure credits and go-to-market resources. These updates are designed to strengthen how partners run their business and accelerate the ability to take solutions to market. We continue to evolve partner benefits packages as a practical growth lever, combining product, support and advisory benefits so partners can invest with confidence.
To enable AI Transformation, Microsoft is introducing program updates and offers in the coming months. These updates are intended to enable partners, including services partners, channel partners and software companies, to build and deliver agents across the Frontier product stack.
- Differentiation via Frontier Partner specialization: The Frontier Badge is evolving into a Frontier Partner specialization. This specialization differentiates partners, including services partners and channel partners, who demonstrate capabilities to build or deliver agents across Microsoft’s Frontier product stack. It creates a clear way for customers and Microsoft field sales teams to identify partners with validated readiness for agentic AI scenarios.
- Updated Frontier Distributor designation: Microsoft is evolving the Frontier Distributor designation to reflect distributor capabilities that matter for scaling agentic AI across the channel. For partners, this will make it easier to identify distributors that can deliver repeatable skilling, enablement to build and manage agents and Marketplace-backed motions to transact and grow agent sales.
- Benefits for software companies building AI apps and agents via App Accelerate: App Accelerate supports software companies building AI apps and agents on the Microsoft agent stack, with benefits designed to bring agentic solutions to market with strong foundations for trust.
Investments in skilling
This year we are investing in partner skilling that connects certification readiness to project-ready execution, with role-based experiences like Project Ready Workshops that translate skills into repeatable delivery practices. These learning experiences are delivered through our Partner Skilling Hub.
We are also introducing the Frontier Engineer Badge, a new learning path delivered through Titan Academy that prepares Solution Engineers and Solution Architects within the partners’ organization to design, build and operate production-ready agentic AI solutions across the Frontier Transformation stack, including Microsoft Copilot, Copilot Studio, Azure AI Foundry, GitHub Copilot, Microsoft Fabric and Agent 365.
The journey is hands-on by design and follows a three-part model: earn required certifications to establish a shared technical baseline, demonstrate delivery capability through Project Ready (building and integrating agents with governance, security and compliance) and build advanced readiness for operating at scale through governance, velocity and industry solution patterns. The outcome is clear: delivery-ready engineers who can move customers from prototypes to trusted, governed deployments.
Capturing the Marketplace opportunity
Marketplaces matter more in 2026 as customers consolidate procurement and expect faster time to value, especially as AI moves from pilots to production. With over 5,000 AI solutions available, Microsoft Marketplace increases discoverability for partner-built AI solutions, including agents, and supports a more repeatable buy-and-deploy motion through familiar procurement. It also makes it easy for partners to package multiparty software and services offers, so customers can purchase what they need to implement, govern and scale AI in production.
Omdia projects Microsoft Marketplace as a nearly $300 billion partner services opportunity by 2030. In the same study, partners selling through Marketplace reported go-to-market benefits, including faster sales cycles and larger deals, with 75% of study participants reporting faster closes and 69% reporting larger deals through Microsoft Marketplace.(5)
To accelerate demand generation and make it easy to activate these motions, we recently introduced Partner Marketing Center Pro, an AI-powered experience for end-to-end campaign creation. It brings campaign discovery, customization and co-branding, intelligent localization and translation, automated publishing and built-in reporting into one workflow, with an AI assistant that provides coaching throughout the process.
Partner Marketing Center Pro is a benefit of the Microsoft AI Cloud Partner Program available to partners who have purchased at least one partner benefits package, who have attained a Solutions Partner designation or who are currently enrolled in ISV Success.
Ways to engage now
Here are a few practical next steps partners can take to maximize their Microsoft investment:
Start by joining the Microsoft AI Cloud Partner Program.
- Plan to attend our annual sales kickoff for partners, virtually on Wednesday, July 22, 2026, to learn more about FY27 priorities and execution motions.
- Explore partner benefits packages and select the option that aligns to their growth plan.
- Pursue a Solutions Partner designation or specialization that matches their solution plays and customer demand.
- Visit the Partner Skilling Hub to find role-based learning resources.
- Launch an FY26 campaign focused on SMB, security, Copilot adoption or marketplace growth using Partner Marketing Center Pro.
Making Frontier Transformation real
Frontier Transformation is about building AI-powered operating capability grounded in intelligence and trust, and delivered consistently across industries, geographies and market segments. Partners make that real for customers by turning strategy into production-ready solutions, with governance, security and adoption built in from day one.
Microsoft is committed to partner success. We will continue investing in the Microsoft AI Cloud Partner Program, with the incentives, the skilling and the go-to-market capabilities that enable partners to build repeatable offers, increase discoverability and deliver trusted AI outcomes for customers at scale.

Error converting python DataFrame to Table
I have used the following commands to load in a python .pkl file.
fid = py.open("data.pkl");
data = py.pickle.load(fid);

Error using py.pandas.DataFrame/table
Dimensions of the key and value must be the same, or the value must be scalar.
What does this error mean? I’m guessing it’s because the DataFrame object in the .pkl contains a couple nested fields. Most of the fields are simply 1xN numeric vectors, but a couple are 1xN objects which then have their own fields.
How can I convert this DataFrame object to something usable in MATLAB?

Microsoft 365 Quarterly Uptime Number Sinks to New Low
Microsoft 365 Uptime Suffers Major Blip in First Quarter of Calendar Year 2026
Microsoft’s service health and continuity page publishes details of Microsoft 365 Service Level Availability on a quarterly basis. The figures are worldwide for all commercial regions and reflects the combined uptime performance across all workloads. Microsoft doesn’t report details of uptime performance for individual regions. In effect, the figure is a metric for reporting and transparency purposes at a very high level instead of detailed information about a single tenant or even tenants in a single country.
Lowest Uptime Number Ever
The 99.526% figure published for Microsoft 365 uptime in the first quarter of the 2026 calendar year came as a real surprise because it was such a big drop over the performance delivered in the previous quarters (Figure 1).
Delivering 99.526% uptime means that service interruptions clocked up approximately 614 minutes (just over ten hours) in the quarter. Not only was the figure well below the norm (performance in Q4 CY2025 was 99.954%), but it also marked the lowest figure for uptime performance since the Office 365 for IT Pros team began to track the data in 2013 (Table 1).

Microsoft’s published data for Microsoft 365 uptime only goes back to 2022, but we’ve noted the quarterly performance ever since Microsoft introduced its financially-backed guarantee for the Office 365 service (as it was at the time).
Impact on Uptime Doesn’t Mean Any Service Credits
A large drop in uptime performance in Q1 might seem staggering, but it is only an indicator that one or more largescale incidents occurred, perhaps in several regions. Certainly, the impact of the incidents was sufficient to materially affect the global uptime metric. It also doesn’t mean that Microsoft is on the hook to pay out service credits to its customers under the service level agreement for online services. When reading Microsoft documentation about availability, you might find this page to be a useful guide to how Microsoft thinks about Service Level Agreements.
Although Microsoft’s commitment is to deliver 99.9% uptime for its online services, the measurement on a per-service, per-month basis. Indeed, Calling Plans, Teams Phone, and Audio Conferencing go even higher with a 99.999% uptime, up from the 99.99% target set in 2021.
Customers can only claim service credits if a specific service like Exchange Online or SharePoint Online falls below the 99.9% threshold with the uptime percentage calculated as:
Delivering 99.526% uptime means that service interruptions clocked up approximately 614 minutes (just over ten hours) in the quarter.

Table 1: Microsoft 365 SLA performance since 2013 (from Office 365 for IT Pros)
Microsoft’s online data only goes back to 2022, but we’ve noted the quarterly performance ever since Microsoft introduced its financially-backed guarantee for the Office 365 service (as it was at the time).
Impact on Uptime Doesn’t Mean Any Service Credits
A large drop in uptime performance in Q1 might seem staggering, but it is only an indicator that one or more largescale incidents occurred, perhaps in several regions. Certainly, the impact of the incidents was sufficient to materially affect the global uptime metric. It also doesn’t mean that Microsoft is on the hook to pay out service credits to its customers under the service level agreement for online services. When reading Microsoft documentation about availability, you might find this page to be a useful guide to how Microsoft thinks about Service Level Agreements.
Although Microsoft’s commitment is to deliver 99.9% uptime for its online services, the measurement on a per-service, per-month basis. Indeed, Calling Plans, Teams Phone, and Audio Conferencing go even higher with a 99.999% uptime, up from the 99.99% target set in 2021.
Customers can only claim service credits if a specific service like Exchange Online or SharePoint Online falls below the 99.9% threshold with the uptime percentage calculated as:
Claims cannot be made based on quarterly performance nor across multiple workloads. Given the work involved to gather evidence and logs, many tenants don’t bother pursuing claims, and to be fair to Microsoft, the uptime performance for online services is usually very good.
Spread of Microsoft 365 and Large Number of Users Makes Uptime Hard to Imagine
According to Microsoft’s FY26 Q2 results, Microsoft 365 now “exceeds 450 million paid seats” Taking the uptime calculation for a service, each user had 129,600 minutes to access online services in Q1 CY26. Microsoft 365 as a whole has 58.32 trillion user minutes. Losing 0.00474% of those minutes means that Microsoft 365 tenants as a whole lost approximately 276 billion user minutes in the quarter (by comparison, the figure for Q4 CY25 is approximately 27 million).
Microsoft 365 service interruptions happen all the time. The question is whether an outage affects your tenant. Given the distributed nature of the Microsoft 365 datacenter network, high availability features incorporated into workloads (like Exchange Database Availability Groups), and the distribution of tenants and workloads across the network, a single outage seldom affects more than one region. The blip in uptime availability in Q1 CY26 is a blip, but no more than that. At least, that’s what the historic uptime data tells us. Time will tell.

How to put a title on a colorbar?
I have a 3D surface surf(X,Y,Z) viewed from view(0,90) with a colorbar which I want to put a title on. The help instructions talk about an lcolorbar, TitleString and ZlabelString but there’s no example and I’m lost.
[X Y]=meshgrid(0:100,0:100);
Z=Y;
surf(X,Y,Z);
view(0,90);
hcb=colorbar;
?????? what next to put a title on the colorbar please ?????
Maybe something like set(get(hcb,’Title’),’cb title’) but I wouldn’t be asking if that worked …

UAV Toolbox Support Package for PX4 Autopilots — SITL plant simulation running much slower after recent windows update
I’ve been developing a custom controller using this toolbox, and everything has been working well after following the examples provided in the documentation.
However, after this last Tuesday, April 14th 2026, I attempted to monitor and tune my controller, and it threw an error saying the build failed and I need to go through the toolbox setup again (this is the first time I’ve gotten this error). I did this, and that is when problems developed. When using a simulink plant simulation for the PX4 SITL Host, the plant can no longer run in real time. It runs at about a quarter of the speed. I booted up the PX4 monitor and tune with plant example, and even that example is now running slowly too! Is it possible the recent security update affected TCP communication between Windows and the WSL network adapter?
