Reply-To’ Header Being Stripped in Office 365 Emails
Hi everyone, we are experiencing an issue where the “Reply-To” header in emails sent to our Exchanged hosted email account is being stripped. This behaviour started on the 7th of August, seemingly for reasons we haven’t been able to isolate.
Our current set up is that we have one primary email address that we receive all of our customer enquiries, orders, and emails through for 15+ websites. This email address is hosted through Exchange and we have set up SMTP. Our website is a WordPress based website, and we use WP Mail SMTP to connect our Exchange account to this plugin. Then, we filter this email account through MailGuard so that we mitigate 99% of the spam sent to that address.
Originally, we thought the problem was to do with this plugin, so we rolled back a version of the plugin and the issue was still not rectified. We also reached out to MailGuard asking them if they would strip Reply-To headers before they sent the email(s) back to us, and their reply from support was:
“We will add details into the headers of an email, but that will be in regards to recording the Hops of the email, whether it has passed SPF/DKIM/DMARC checks and specific logging regarding tour processing of the email.
That all being said, MailGuard’s systems do not remove content from emails.
If the emails do not have a reply-to in them, that is how they are when we have received them.”
As mentioned, we have 15+ other websites, but only 2 of them run through an OAuth connection with Exchange through the WP Mail SMTP plugin. The other websites, use Brevo (SendInBlue) as their SMTP provider.
Thinking it was a plugin issue, we tested the enquiries being sent from those websites to our email address, to see if they were also getting their Reply-To headers stripped, however, none of them were having this issue. We use the free SMTP service through Brevo for these smaller sites, and would exceed their limit if we switched our main sites to Brevo in the meantime.
We believe we have isolated the issue down to Exchange/Office365, but admittedly, are finding it a bit of a challenge given the intricate settings and options available throughout the account.
Below is a screenshot of two enquiries sent through to our email address, but 24 hours apart. The left indicates the the Reply-To header is present as normal, but the right image, indicates a missing Reply-To header.
To add a note, it is interesting saying that the emails were not signed. We definitely have DMARC/DKIM DNS records present so I’m unsure why they would be being delivered as unsigned.
We have not changed any SMTP settings, any policy settings, mail rules or anything similar in our Exchange account. It seemingly appears to be an issue that randomly appeared overnight.
Has anyone experienced similar issues with “Reply-To” headers being stripped in Office 365? Could there be specific settings or policies in Exchange Online or Azure that might affect this behaviour? Any advice or troubleshooting tips would be greatly appreciated.
Thank you in advance for your help.

Exchange hybrid writeback with cloud sync is enabled, but I still can’t edit attributes from 365…
Hi,
I’m very familiar with Exchange hybrid mode, I did a lot of hybrid migration, and I’m waiting since very long time for Exchange Hybrid Writeback feature to be able to edit hybrid Exchange mailbox settings from Exchange Online Admin Center instead of having to connect to the on-prem hybrid server or to “Exchange Recipient Admin Center”. I did configure it with Cloud Sync, enabled Exchange Hybrid Writeback option like in the following article (Exchange hybrid writeback with cloud sync – Microsoft Entra ID | Microsoft Learn), but I still can’t edit any mailbox attributes that comes from the on-prem AD, like emails adresses (aliases), etc. I still receive the same old error message saying “ Unable to update the specified properties for on-premises mastered Directory Sync objects or objects currently undergoing migration. DualWrite (Graph) RequestId: 4c2d42fa-9c6e-4749-8d00-79e9f8041787 The issue may be transient and please retry a couple of minutes later. If issue persists, please see exception members for more information.”
Am I misunderstanding how it is supposed to work? I searched a lot on the web, and even if it seems to be a very valuable feature, not much poeple talk about it, and when they talk about it, they don’T make a demo of how to use it once it is configured.
Thanks!

Need Fans Blasting Cold Air to Sleep peacefully.
I am seeking assistance to troubleshoot an issue I am experiencing with my computer. I have enabled S3 sleep mode in the BIOS and restored all settings to factory defaults. Additionally, I have disabled modern standby, hibernate, and fast startup settings using various methods such as Group Policy Editor, Registry Editor, and Power Options. Despite this, the problem persists. I strongly believe it is a software-related issue. Can someone provide guidance on how to resolve this?

A notification from the update center indicates that a program update is available.
I have been receiving notifications from the system regarding updates for some of my programs. For instance, yesterday, I received a notification about an update for Corel VideoStudio X10. However, when I clicked on it, the notification disappeared. How can I check which programs have updates and how can I proceed with updating them? I tried searching online but all I found were results related to Windows 11 updates, which is not what I am looking for. I specifically need guidance on updating individual programs. Thank you for your assistance.

FAQs on Installing Windows 10 and 11 via Windows To Go on External Drives
Greetings,
I am seeking guidance on the installation of Windows on external devices and would appreciate any assistance you can provide. My goal is to create a universal external device that contains installations of Windows 10 and 11 with a digital license purchased for a third party, using the information provided by them such as name, mobile number, and Gmail address.
1. Is it feasible to install Windows 10 and 11 on a new external device that is associated with a digital license linked to a Microsoft account different from the one on the host device to which the external device will be connected? Can I carry out this process on my desktop PC?
2. Will these external devices function properly on the third party’s PC who has shared their details with me?
3. To clarify further, I am looking to create a commercial external device on which Windows 11 and Windows 10 will be installed with a digital license connected to a Microsoft account, using the details provided by a third party. Is it possible to set this up on my desktop PC?
4. If the answer to the above questions is negative, are there any alternative solutions for creating a universal external device, possibly utilizing a local account of the third party and activating the digital license, so that the prepared device can be sold to them with the purchased license?
5. If the solution is affirmative, will the Microsoft server check my PC details and hardware configuration instead of those of the third party?
Thank you for your attention.

Exploring new applications and updates on Windows 11
Good day everyone! I’ve made the choice to switch from W10 to W11 due to an issue with an installation that disrupted Aquasuite’s access to my hardware. Previously, I relied on Acronis Try and Decide to evaluate installations and changes to my system in a safe environment. Unfortunately, Try and Decide is not compatible with W11. How can I effectively test product installations or updates and revert back to a previous state?
One option is to conduct a full backup and recovery.
Alternatively, are there any other suggestions or methods you recommend for achieving this?

Uncertain of the Cause: Black Screen
Seeking advice…
As I worked on editing photos on my computer with music in the background, the screen suddenly went dark but the music kept playing. Upon pressing Ctrl Alt Delete, the menu displayed on the screen as usual. Opting to log out, I expected to see the login screen, but it wasn’t visible.
Thinking a thorough cleaning might help, I powered off the PC, unplugged it, and carefully removed and cleaned the graphics card and memory components before reassembling everything. However, upon powering it back on, the monitor received no signal.
After rechecking that all components were properly seated, I tried again, but alas, the monitor remained blank.
The PC seems to be functioning fine, only the screen shows no activity. It worked momentarily after using Ctrl Alt Delete to end the session, leaving me puzzled. Could this be a sign of a failing graphics card? I am uncertain, as the issue arose right after it initially appeared to be resolved. Any insights on what might be causing this perplexing situation?

I have reinstalled Office 365 twice and that has not fixed the problem. Help me, please, if anyone can. Thanks

Return a value from a list based on the value of another cell
I am working on a schedule.
I have one master spreadsheet I want to input all my employees working on the shift in specific positions for the entire year.
I have other spreadsheets for each individual area. I want the area spreadsheets to populate from the master based off the date input on the area sheet.
So if BOB works on 1/1/24 in Area 1, spot 1 on the master sheet, I want to put the date into a cell on the area sheet and have BOB populate in the Area 1, spot 1 on the area sheet.
I hope this makes sense.
On the master sheet, the dates are across the top, and the positions are listed in the columns.

Protecting Specific Tabs in a Workbook from Viewing
Hi,
I am trying to see if there is a way to protect/block specific tabs in an Excel workbook from viewing, not just editing. And is there a way to give different permissions/vies/access to different users within the same workbook?
For Example on below spreadsheet, I would like some users to be able to view just the 1st and 2nd tab and not the Budget tab. And have other be able to view all other tabs.
I would appreciate any help or insight.

Outlook desktop client is encrypting emails despite the sensitivity label setting
We have 3 different sensitivity labels set up – General, Internal and Confidential. The General label does not encrypt content, internal and confidential do. The default label for emails is Confidential.
When someone uses the Outlook Desktop client (release 2407) and switches from Confidential to General, the email is still encrypted. This doesn’t happen with the Outlook web client. If the switch from Confidential to Internal and then to General, the email is not encrypted.
Has anyone else seen this behavior?

Fitting multiple datasets with unique parameters using lsqcurvefit to a normalized function and constraints between datasets.
Thank you for taking the time to help. I will do my best to be clear and concise.
I have 3 sets of data (atttached), each with x and y data – not necesarilly the same length.
Each y(x) function can be normalized into p(t) using 4 parameters:
A – a constant that is extracted from each individual y(x), ‘A’ looks like [A1, A2, A3]
B – a fitting parameter unique to each y(x)
C – a fitting parameter applied to all y(x)
D – a constraint variable dependent on A and B applied to all y(x)
So the set looks something like:
I would like to use lsqcurvefit to fit my data to my function p(t) and output the unique (C and D) values.
I have a final constraint to increase the accuracy of lsqcurvefit: , where D is another global constant like C.
Where I’m at now, I want to adjust C and D to fit my function p(t) to y(x), but I don’t know how to also include the unique A values for each y(x).
I’ve pasted my current code below where I am able to get an individual fit for each y(x) but without consistent C and D parameters.
%% Data analysis
Results = NaN(3,2); % Result [C,D] for each individual fitting
for t = 1:3
%TL is summary matrix of all y(x) for the 3 experiments, NaN fills in
%where some y(x) are shorter than others.
x = TL(~isnan(TL(:,2*t-1)),2*t-1); %extracts x values from TL
y = TL(~isnan(TL(:,2*t)),2*t); %extracts y values from TL
%P = parameters: P(1) = C | P(2) = D
%fun below is the normalization for p(t)
fun = @(P,x)A(t)*(1-1/(2*(1-P(1))))*(1.304*exp(-(P(2)*x/(r/1000)^2).^0.5)-0.304*exp(-0.254*P(2)*x/(r/1000)^2))+1/(2*(1-P(1)));
P0 = [0.4, 1*10^-9]; %Initial parameters
lb = [0.1, 1*10^-10]; %Lower bound
ub = [0.5, 1*10^-8]; %Upper bound
Results(t,:) = lsqcurvefit(fun,P0,x,y,lb,ub); %Result consolidation for individual fitting
subplot(3,1,t)
plot(x,y,’ko’,x,fun(Results(t,:),x),’b-‘)
end
From looking at other posts on using lsqcurvefit with multiple datasets, I think my obstacle has come down to whether I should (1) run lsqcurvefit on all y(x) and somehow input the unique A constants or (2) run lsqcurvefit on individual y(x) and somehow correlate C and D to match between each fitting.
I hope this is presented clearly, looking forward to your thoughts and discussion – Thanks.Thank you for taking the time to help. I will do my best to be clear and concise.

From looking at other posts on using lsqcurvefit with multiple datasets, I think my obstacle has come down to whether I should (1) run lsqcurvefit on all y(x) and somehow input the unique A constants or (2) run lsqcurvefit on individual y(x) and somehow correlate C and D to match between each fitting.
I hope this is presented clearly, looking forward to your thoughts and discussion – Thanks. Thank you for taking the time to help. I will do my best to be clear and concise.
I have 3 sets of data (atttached), each with x and y data – not necesarilly the same length.
Each y(x) function can be normalized into p(t) using 4 parameters:
A – a constant that is extracted from each individual y(x), ‘A’ looks like [A1, A2, A3]
B – a fitting parameter unique to each y(x)
C – a fitting parameter applied to all y(x)
D – a constraint variable dependent on A and B applied to all y(x)
So the set looks something like:
I would like to use lsqcurvefit to fit my data to my function p(t) and output the unique (C and D) values.
I have a final constraint to increase the accuracy of lsqcurvefit: , where D is another global constant like C.
Where I’m at now, I want to adjust C and D to fit my function p(t) to y(x), but I don’t know how to also include the unique A values for each y(x).
I’ve pasted my current code below where I am able to get an individual fit for each y(x) but without consistent C and D parameters.
%% Data analysis
Results = NaN(3,2); % Result [C,D] for each individual fitting
for t = 1:3
%TL is summary matrix of all y(x) for the 3 experiments, NaN fills in
%where some y(x) are shorter than others.
x = TL(~isnan(TL(:,2*t-1)),2*t-1); %extracts x values from TL
y = TL(~isnan(TL(:,2*t)),2*t); %extracts y values from TL
%P = parameters: P(1) = C | P(2) = D
%fun below is the normalization for p(t)
fun = @(P,x)A(t)*(1-1/(2*(1-P(1))))*(1.304*exp(-(P(2)*x/(r/1000)^2).^0.5)-0.304*exp(-0.254*P(2)*x/(r/1000)^2))+1/(2*(1-P(1)));
P0 = [0.4, 1*10^-9]; %Initial parameters
lb = [0.1, 1*10^-10]; %Lower bound
ub = [0.5, 1*10^-8]; %Upper bound
Results(t,:) = lsqcurvefit(fun,P0,x,y,lb,ub); %Result consolidation for individual fitting
subplot(3,1,t)
plot(x,y,’ko’,x,fun(Results(t,:),x),’b-‘)
