Determine the Bode diagram or a transfer function with input output data without tfest
In a partially unknown system, I measured a square-wave signal as input and the associated system response. Now I would like to use fft() to determine the transfer function or the Bode diagram. I have attached the measurements. I have the following code (also from this forum) but it results in this very bad bode plot. where is my mistake?
input = x3bzeit((23000:39000),2);
output = x3bzeit((23000:39000),3);
time = x3bzeit((23000:39000),1)*10^(-6);
Fs = 1/mean(diff(time)); % Sampling Frequency
Fn = Fs/2; % Nyquist Frequency
L = numel(time);
FTinp = fft(input)/L;
FTout = fft(output)/L;
TF = FTout ./ FTinp; % Transfer Function
Fv = linspace(0, 1, fix(L/2)+1)*Fn; % Frequency Vector
Iv = 1:numel(Fv); % Index Vector

plot(Fv, 20*log10(abs(TF(Iv))))

Duplicate Mail User Objects Created for Guest Accounts
EX1015484 Issue Causes Duplicate Exchange Online Mail User Objects Linked to Entra ID Guest Accounts
I am indebted to MVP Joe Stocker for sharing information about incident EX1015484 (duration from February 20 7:38AM PST to February 27 5AM PST). The problem as reported by Microsoft (Figure 1) is that when administrators create new Entra ID guest accounts, duplicate objects appear in Exchange Online that prevent email delivery to the guest accounts.
Creating Mail User Objects
Entra ID and Exchange Online use a dual-write mechanism to update objects. Guest accounts originate when external users are added to Teams or Microsoft 365 groups, or when an administrator invites an external user to join the tenant from the Entra admin center.
When Entra ID creates a new guest user account, Exchange Online creates a mail user object. The existence of the mail user object allows guest users to be included in distribution lists. The mail user object has an email address, so email can be sent to the object, and the transport system is able to route messages to the guest account. Exchange Online removes a mail user object automatically following the removal of the guest user account from Entra ID. If the deleted Entra ID account is restored, the mail user object reappears.
Duplicated SMTP Addresses
In the case of EX1015484, it seems like Microsoft shipped a feature update with a bug that created mail user objects with duplicate SMTP email addresses. The Exchange transport system insists that email-enabled objects have unique email addresses because that’s the basis for routing messages to their final destinations.
Apparently, tenants need to contact Microsoft support to remove the duplicate objects. You can’t just remove duplicate mail user objects because of the dual-write mechanism. Entra ID is the directory of record, so any attempts to run Remove-MailUser to delete an object linked to a guest account will fail:
Remove-MailUser -Identity a9f35d52-572e-4438-a129-08d8c00ae88b Confirm Are you sure you want to perform this action? Removing the mail enabled user Identity:"a9f35d52-572e-4438-a129-08d8c00ae88b" will delete the mail enabled user and the associated Windows Live ID "elifon_contoso.com#EXT#office365itpros.onmicrosoft.com". [Y] Yes [A] Yes to All [N] No [L] No to All [S] Suspend [?] Help (default is "Y"): y Remove-MailUser: ||An Azure Active Directory call was made to keep object in sync between Azure Active Directory and Exchange Online. However, it failed. Detailed error message: Resource 'a9f35d52-572e-4438-a129-08d8c00ae88b' does not exist or one of its queried reference-property objects are not present. DualWrite (Graph) RequestId: 61220f4c-90ea-4fa5-bf1f-c07b5d10c26d The issue may be transient and please retry a couple of minutes later. If issue persists, please see exception members for more information.
Removing the guest accounts from Entra ID and restoring them after a few minutes might well work. I can’t say because the problem didn’t affect any tenant that I have access to.
In any case, Joe posted some PowerShell to find mail-enabled objects with duplicate SMTP addresses:
Connect-ExchangeOnline; Get-Recipient -ResultSize unlimited | Select-Object -ExpandProperty EmailAddresses | Where-Object {$_ -like "smtp:*"} | Group-Object -Property {$_.ToString().ToLower()} | Where-Object {$_.Count -gt 1} | Select-Object @{Name="SMTPAddress";Expression={$_.Name.Substring(5)}}, Count | Sort-Object -Property Count -DescendingThe code is faster when a filter is applied to select mail user objects. Here’s my version:
Connect-ExchangeOnline;
Get-ExoRecipient -RecipientTypeDetails MailUser -ResultSize unlimited | Select-Object -ExpandProperty EmailAddresses | Where-Object {$_ -like "smtp:*"} | Group-Object -Property {$_.ToString().ToLower()} | Where-Object {$_.Count -gt 1} | Select-Object @{Name="SMTPAddress";Expression={$_.Name.Substring(5)}}, Count | Sort-Object -Property Count -Descending
I tested the amended code by removing the check for addresses with a count greater than 1, so I am pretty sure that it works. Feel free to improve the code!
Problems Happen
It’s regrettable that EX1015484 happens, but that’s the nature of software. The issue has been resolved, and you will no longer encounter mail user objects with duplicate SMTP addresses in your tenant. It’s worth running the code shown above just in case that the problem hit your tenant and left some bad objects behind.
So much change, all the time. It’s a challenge to stay abreast of all the updates Microsoft makes across the Microsoft 365 ecosystem.

Legends using bodeplot with latex interpretation
Hi, I am trying to write code for plotting frequency responses and cannot get the legend to accept latex formatting. I know there are issues with all of these signal processing tools and stuff like legends, but if I open the figure in a new window and manually adjust the legend in the property editor then it is possible. So there must be a work around. Here is one of the many iterations I have used, in this version the legend appears, but as soon as I add interpreter to the command then I get errors such as seen below:
G1 = G(1,1);
G2 = G(1,2);
G3 = G(2,1);
G4 = G(2,2);
names = {‘$G_{11}$’, ‘$G_{12}$’, ‘$G_{21}$’, ‘$G_{22}$’};
LegendValues = string(names);
bp = bodeplot(G1, G2, G3, G4);
opts = bodeoptions;

Artificial Intelligence and Microsoft 365 Administration
Artificial Intelligence and PowerShell for Tenant Administration – An Unlikely Couple?
I’ve been asked by a few people to comment about Lokka, the new creation of Merill Fernando, a program manager in the Microsoft Entra ID group. Lokka is a proof of concept exploring how the combination of AI Large Language Models (LLMs) and the Model Context Protocol (MCP) can bring value to Microsoft 365 administration. In this case, by generating Graph API queries in response to administrator prompts. For example, “How many user accounts belong to the marketing or sales departments.”
Merill’s a very inventive individual whose capacity to invent extends to his eye-catching tweet asking the question if Lokka is the end of PowerShell for Microsoft 365 administrators (Figure 1).
Helping Administrators with Simple Queries and Examples
Of course, the advent of a proof of concept like Lokka doesn’t mean that Microsoft 365 administrators suddenly need to lose all interest in PowerShell. AI tools can certainly be helpful in responding to queries that aren’t covered by the standard admin center GUI. They can also educate administrators by showing them how to use PowerShell to run Graph AI queries.
The Exchange Server 2007 product was the first Microsoft server to embrace PowerShell. One of the brainwaves in that product was how the Exchange Management Center (EMC) console displayed the PowerShell code it executed when it performed actions. Figure 2 shows how the EMC in Exchange Server 2007 displayed the code used to create a new mailbox.
Seeing the PowerShell code in action and being able to copy the commands for reuse helped administrators master basic PowerShell command for managing Exchange servers. Another example is how Merill’s Graph X-Ray tool gives administrators a glimpse into the Graph API requests run to perform some actions in the console.
Artificial Intelligence and PowerShell in the Microsoft 365 Admin Center
The Microsoft 365 admin center already has Copilot assistance that’s added automatically when a tenant buys some Copilot for Microsoft 365 licenses (Figure 3). The implementation is much like a Copilot Chat session where an administrator prompts Copilot for some information and receives a response containing instructions and possibly some PowerShell code. I imagine that the content used by Copilot is a restricted set of documentation, just like you can restrict a Copilot agent to reasoning over certain SharePoint and external web sites when it composes its responses.
The Importance of Training Material
There’s no doubt that we will see increasing use of AI to assist administrators with tasks as time progresses. The assistance will become more comprehensive, intelligent, and useful. However, the usefulness of any generative AI tool is bounded by the material used to create its LLMs. This means that the answers that an administrative agent can give, whether how-to instructions or PowerShell code snippets, depend on text scanned to build the LLM. If an answer exists to a question, the AI can respond. This includes incorrect answers because the LLM doesn’t know if content contained in source material is accurate. And if an answer isn’t available, the AI cannot respond without hallucinating. For example, Copilot has been known to include the names of PowerShell cmdlets that don’t exist in its responses.
The current set of AI tools we have don’t include insight or creativity. They can respond to known problems, but even so, responses are often based on whatever the most common answer is found in its source material. Those answers might be inefficient. Take the code suggested in Copilot’s response in Figure 3.
Get-MgUser | Where Department eq "Sales"
Several problems exist with the answer. First, the syntax is incorrect and won’t work because the piping to the Where-Object cmdlet is wrong (probably because Copilot absorbed an incorrect answer from some source). Second, the Department property is not retrieved by the Get-MgUser cmdlet unless explicitly requested.
Get-MgUser -Property Id, Displayname, Department | Where-Object {$_.Department -eq "Sales"}Third, it’s always better to use a server-side filter to retrieve PowerShell objects. And in the case of user accounts, it’s also a good idea to filter out guest accounts.
Get-MgUser -Filter "Department eq 'Sales' and userType eq 'member'"
The takeaway is that generative AI can only be as good as the material used for its training. The current state of the art is such that AI can’t recognize when its output is incorrect.
PowerShell Still an Essential Tenant Management Skill
Even with the prospect of better, more complete, and more comprehensive AI tooling on the horizon, I still believe that Microsoft 365 administrators should take the time to acquire a working knowledge of PowerShell. For the foreseeable future, AI might well offer help to those who don’t even know how to start using PowerShell to manage a tenant.
Experience to date demonstrates that AI is unlikely to master the creativity that’s often needed to create something like a full-blown tenant licensing report, complete with costs anytime soon. Combining data from multiple sources to deliver a solution requires more ingenuity than running straightforward Graph requests. I await to be proven wrong that artificial intelligence and PowerShell can do more than perform straighforward, mundane tasks. In the interim, using GitHub Copilot to accelerate the development of PowerShell scripts might be the most productive way to use AI to improve Microsoft 365 automation.

Massive slowdown for Apple Silicon in computing SVD
I recently notice that there is an extreme slowdown in my version of Matlab while computing an SVD when the size of the matrix crosses some threshold. I came up with the following example that demonstrates my issue:
N = [10000 11000 12000 13000];
for i = 1:4
A = randn(N(i),3);
tic;
[U,S,V] = svd(A,0);
toc;
end
When I run this in Matlab R2024b (macOS Apple silicon), the output is:
Elapsed time is 0.000396 seconds.
Elapsed time is 0.000275 seconds.
Elapsed time is 0.000264 seconds.
Elapsed time is 0.083150 seconds.
Of course the exact numbers vary trial to trial, but the speed for the last run (where N = 13000) is consistently orders of magnitude slower.
When I run this same code on Matlab R2024b (Intel processor) on the same computer, this slow down does not happen. I was able to replicate this issue across two different Macs (one with M1 and another with M3) and different versions of Matlab (going back to R2023b).
Any idea why this might be happening in the silicon version?

How to Stop People Using ChatGPT with OneDrive for Business Files
Block ChatGPT Access to OneDrive Files
ChatGPT allows people to connect their personal and work OneDrive accounts. Connecting to OneDrive doesn’t mean that ChatGPT can reason over OneDrive files in the same way that Microsoft 365 Copilot can when it generates responses. However, it does mean that users can upload files from OneDrive to interact with their content through ChatGPT. Figure 1 shows ChatGPT summarizes the content of a file uploaded from OneDrive for Business.
Of course, people shouldn’t store very confidential and sensitive information in OneDrive for Business accounts, but they do. And the temptation to use ChatGPT is obvious when the price of a Microsoft 365 Copilot license is high, so what can organizations do to stop this behavior.
ChatGPT Cannot Access Protected Files
One way to block ChatGPT access to OneDrive for Business is to encrypt the files with sensitivity labels. ChatGPT cannot process these files even after the owner of the file uploads them to ChatGPT. Sensitivity label encryption is based on rights management, and ChatGPT cannot authenticate with the rights management service to obtain the use license necessary to access files protected with sensitivity labels. That’s a pretty effective way to stop ChatGPT opening the file to copy its contents into memory to reason over the data. Microsoft 365 Copilot Chat faces much the same barrier if the sensitivity label assigned to a file doesn’t grant the EXTRACT usage right to the signed-in user (the new DLP policy for Microsoft 365 Copilot also uses sensitivity labels but blocks access in a different way).
Block Consent for Users
Not every Microsoft 365 tenant uses sensitivity labels, and even users in tenants that do don’t always protect files the way that they should. A more fundamental way to block ChatGPT access to OneDrive is to prevent users from being able to grant consent for apps (Figure 2). Make sure to select the “do not allow user consent” setting or allow consent for “low impact” apps.
If users can grant consent, the first user who attempts to connect their OneDrive for Business account to ChatGPT will create an enterprise app in Entra ID for ChatGPT with permissions to read user data (Figure 3).
This isn’t an abnormal situation because many app publishers (including Microsoft) create enterprise apps in customer tenants in the same way. However, it’s better to have administrative oversight over requests to create new enterprise apps. When created, the ChatGPT app will have a service principal to hold its permissions. The same application identifier (e0476654-c1d5-430b-ab80-70cbd947616a) is used in all tenants.
$ChatGPTApp = Get-MgServicePrincipal -Filter "displayName eq 'ChatGPT'" $ChatGPTApp DisplayName Id AppId SignInAudience ServicePrincipalType ----------- -- ----- -------------- -------------------- ChatGPT db277364-71ae-4fa4-9b02-370699b75a0a e0476654-c1d5-430b-ab80-70cbd947616a AzureADandPersonalMicrosoftAccount Application
App consent events are captured in the audit log and can be checked there.
Track What’s Happening
If the ChatGPT app exists in a tenant, it’s easy to check if anyone is using it by looking for sign-in events in the Entra ID log. Here’s some PowerShell to check the sign-in logs for anyone using the ChatGPT application:
[array]$Logs = Get-MgAuditLogSignIn -Filter "AppDisplayName eq 'ChatGPT'" -All $Logs | Group-Object UserDisplayName | Sort-Object Count -Descending | Format-Table Name, Count Name Count ---- ----- Kim Akers (She/Her) 5 René Artois 4
A more precise version checks for successful sign-ins using the ChatGPT application:
[array]$Logs = Get-MgAuditLogSignIn -Filter "AppDisplayName eq 'ChatGPT' and status/errorCode eq 0" -All
Remove the ChatGPT App
If the ChatGPT app is in use, the easiest way to block ChatGPT access to OneDrive for Business is to remove the service principal for its app:
Remove-MgServicePrincipal -ServicePrincipalId $ChatGPTApp.id
Access won’t terminate immediately because ChatGPT sessions might have obtained access tokens that are still valid, but once those tokens expire (within an hour), ChatGPT won’t be able to authenticate with Entra ID because the enterprise app is no longer present in the tenant. Anyone wanting to use ChatGPT to access OneDrive for Business files after that point will need to seek consent to use the app again. And by now, you’ll have blocked that route!

Depending on business goals, partners may pursue a Solutions Partner designation or specialization, both of which provide tailored benefits to help differentiate their business in a competitive market. Achieving a designation unlocks valuable go-to-market resources, sales support, new incentives and product benefits to help expand customer reach, sharpen skills and drive growth. For software development companies, becoming a Solutions Partner** with certified software*** further enhances market presence by validating software capabilities in high-demand areas.
“Having worked alongside every CEO of Microsoft in my career, I would like to personally congratulate Microsoft for its 50 extraordinary years of driving relentless innovation.”
“Lenovo is proud to be a major part of this amazing journey with Microsoft and we are committed to this partnership for many more decades to come.”
— Yuanqing Yang, Chairman and Chief Executive Officer, Lenovo
For partners holding an Azure designation or Azure specialization, additional incentives are available through Azure Migrate and Modernize and Azure Innovate — both underpinned by Azure Essentials. With comprehensive resources, extensive coverage across scenarios and tailored incentives in one easy-to-navigate hub, Azure partners can better support customers from migration to innovation. Learn more in What’s new for Azure partner-led offerings: ISV Success and specialization updates.
Our program offers benefits for partners aligned to their growth stage and across all customer segments. We have recently made the process of obtaining an Azure Solutions Partner designation more aligned to our partners who specialize in working with small and midsize customers. We are also expanding access to Azure Migrate and Modernize and Azure Innovate incentives for SMB pathways. Read more about the SMB path to Azure Solutions Partner designations.
Cloud Solution Provider is our partner hero motion for small and medium enterprises
In November at Microsoft Ignite, we highlighted the $661 billion total addressable market (TAM) opportunity for SME&C customers in FY25 and beyond. Cloud Solution Provider (CSP) partners are the trusted advisors who serve these customers and accelerate their AI transformation with the value-added services and solutions that create real business impact. CSP is our hero motion that enables those partners to drive this business transformation.
“Our Microsoft partnership has evolved to meet the needs of our business and our partners. Together we’ve been able to support our partners to deliver true solution and value selling, leveraging the robust resources available through Microsoft AI Cloud Partner Program and benefitting from the rich incentives. It has enabled us to drive innovation and deliver exceptional experiences for our partners through our ArrowSphere platform and broader enablement programs to ensure they’re empowered to deliver real customer outcomes. Together, we’re enabling the channel to deliver solutions that deliver real impact for customers around the world.”
— Brendan Murphy, Global Director, Public Cloud, Arrow Electronics
We strive to provide CSP partners with the skilling, capabilities and investments to make this opportunity a reality. So far in FY25, we have:
- focused our incentives to clearly align to our five strategic priorities — Copilot on every device across every role, AI design wins with every customer, securing the cyber foundation of every customer, a focus on migrations and Microsoft 365 execution
- dedicated 70% of our total incentive spend to partners that serve the Small and Medium Enterprise and Customer (SME&C) segment
- introduced a series of new promos, including a new-to-Microsoft 365 E5 offer to enable CSP partners to win new customers
Expanding our portfolio of CSP offers and capabilities is an ongoing priority. We share updates as they become available.
Capturing the marketplace opportunity
As customers increasingly centralize their solution procurement, marketplaces have become the preferred buying platform. For software companies, adopting cloud marketplaces accelerates deal closure and increases deal sizes. Serving as a global B2B commerce engine, our marketplace empowers Microsoft partners to provide solutions to customers worldwide. It offers various sales models: digital direct, through partners or with Microsoft — providing flexibility to align with how customers want to buy and how partners want to sell. Learn more in this recent blog.
Unlocking success through skilling and events
The speed of technology innovation requires continuous learning. To support this, we offer our partners a variety of skilling opportunities, such as our popular in-person Microsoft AI Partner Training Days, designed to help partners develop both technical and sales capabilities.
We are also streamlining and simplifying our skilling portals through initiatives like Microsoft Sales Titan (currently in private preview for CSP Accelerate partners and available for all partners in summer 2025), a program tailored to equip sales professionals with in-depth knowledge of Microsoft Threat Protection SKUs, empowering them to position themselves as industry leaders. Discover these and other skilling opportunities.
Looking ahead, we invite our partners to join us at Microsoft Build, taking place May 19–22, 2025. This flagship event offers an exclusive opportunity to explore the latest advancements in AI, learn how to work smarter and elevate your projects. Connect with peers, industry experts and Microsoft leadership while diving into the code and innovations that will shape the future.
