Make Your Test Data Less Boring with M365Mutator
Testing Microsoft 365 scenarios often involves test data. If the data is stale or always the same, it might not generate good results or help to identify lurking problems. The M365Mutator app helps to solve the problem by mixing things up in your test data. The app can change properties of Entra ID accounts, send email, update calendars, and generally make sure that whatever you’re testing has fresh information to run against. https://office365itpros.com/2026/07/10/m365mutator-test-data/Make Your Test Data Less Boring with M365Mutator

We had a colleague leave who had their work email address and account connected to MANY Power Automate flows, SharePoint, OneDrive, Forms, Excel, etc. We are looking to create a recommendation / best practices for a single account that will be used by the I.T. department for use in Power Automate, etc. We will have colleagues in the I.T. department have access to SharePoint sites (maybe a security issue? do we EACH get our OWN accounts then?) and Power Automate We'd have to have it setup as an email enabled account so we'd have to pay instead of a service account. Other thoughts?
Not For Profit Licence suddenly disappeared and then deleted
Hi All Have a big issue. Have a not for profit account for our charity. Renewed licence earlier in the year and all was ok and working. Then a few days ago I had reports of not being able to access data. After much hunting I found the below. Seems account was suddenly and without warning disabled and then reported as deleted a few days later. What do I do? I desperately need to recover the files that were on the associated teams? Any help would be much appreciated
Unable to access Global Admin, username not recognised, need tenant recovery billing active
Unable to access Global Admin account for Microsoft 365 tenant. Username not recognised and I need tenant recovery. Billing is still active. I am the billing owner of a Microsoft 365 Business subscription for yutoriacupuncture.com.au but I have lost access to all Global Admin accounts. The original admin account email is returning “username may be incorrect”. No other admin or business emails are recognised. I have a business email associated with the admin account i can still log into. I recently briefly cancelled and reinstated my domain which may have affected tenant linkage. I also recently joined a university Microsoft 365 organisation which may be affecting sign-in routing? I have tried login.microsoftonline.com, admin.microsoft.com, password resets, and incognito browsers with no success. I have tried contacting support via phone and email but keeps cutting out, saying it can't identity me, or sends me into a loop hole with the support chat bot. I need Microsoft to escalate this to tenant recovery or Data Protection team to restore Global Admin access using billing and domain ownership verification.
Looking for Microsoft 365 best practices for a large dynamic company group
Looking for Microsoft 365 best practices for a large dynamic company group I'm a Microsoft 365 admin trying to figure out the best architecture for a company-wide group (100+ users) and I'm wondering if there's a better approach than what I'm currently doing. What I need I want a single company group that can: Automatically include users through dynamic membership Share SharePoint sites, files, OneDrive content, Teams resources, etc. Allow sending company-wide emails Allow sending required Outlook meeting invitations (not optional) Have moderation/approval for announcements, meeting invites, or posts Allow certain trusted users to bypass approval while everyone else requires approval Scale as employees are hired/terminated automatically Current setup Dynamic Distribution List Used for company-wide emails and Outlook meeting invites. Membership is dynamic using an Exchange recipient filter based on US users. Private Microsoft 365 Group Used for SharePoint, file sharing, and collaboration. Membership is dynamic through an Entra ID Dynamic Membership Rule. I had to use PowerShell to configure some permissions because the portal didn't support everything I needed. Problems I'm running into I now have two separate groups that should always contain the same people. The Dynamic Distribution List works well for email/meetings but doesn't provide SharePoint, Teams, or file collaboration. The Microsoft 365 Group provides collaboration but doesn't seem to support everything I need for company-wide communication. I haven't found a clean way to have approvers/moderators, while allowing a few designated people to post or send meeting invites without requiring approval. I also haven't found a good way to make Outlook meeting requests "required" from the sender side other than relying on attendees not changing their RSVP. My questions Is there a better Microsoft 365 architecture for this? Should I be using a Dynamic Distribution List, a Microsoft 365 Group, a Mail-enabled Security Group, Teams, Viva Engage, or something else? Is there a supported way to have dynamic membership + SharePoint + company email + moderated announcements/meeting invites all in one solution? How do large organizations typically handle company-wide communications while keeping membership automatic? Is maintaining two dynamic groups (one for collaboration and one for email) simply the recommended approach? I'd love to hear how other Microsoft 365 admins have solved this in production. Thanks!Moving Office 365 Mailboxes to IMAP Servers - What’s the Best Approach
I’ve recently been looking into scenarios where organizations need to move mailboxes from Microsoft 365 to IMAP based email servers, and I noticed this is still a common requirement in many migrations. In most cases, the challenge is not just moving emails, but making sure everything like folder structure, old emails, and user data stays intact without creating too much disruption for users. From what I’ve seen, doing this manually can get very complex, especially when there are multiple mailboxes or large data volumes involved. That’s where migration tools usually come into the picture. Most tools simplify things by handling: 1. Secure connection to Microsoft 365 accounts 2. Bulk mailbox migration 3. Preserving folder hierarchy 4. Reducing downtime during the move 5. Avoiding duplicate data issues One thing I’ve noticed is that running a small pilot migration first always helps. It gives a clear idea of how the actual migration will behave before moving all users. Has anyone here worked on Office 365 to IMAP migration at scale? Would be good to know what approaches or tools worked best in your case and what challenges you faced during the process.
Access VBA performance dramatically slowed since June Update
We are running an access based application with a large vba project. One customer with four different instances of this project experience extreme slow down in performance on all instances during the last week. We made no changes. The Microsoft Office Update was applied automatically. We believe the problem happened then. We have tried reverting to several different previous versions of Office but symptoms still remain.
