Setting for Outlook Classic, New Outlook and Windows or Outlook Web. Need Microsoft recommendation on this one.How to Update Teams Settings After Transferring Meetings
When discussing the transfer ownership of calendar events, we pointed out the Teams meeting problem. Essentially, if an event is a Teams meeting, details of the online meeting are not updated to allow the new owner to control its settings. The result is that recordings and other online meeting artifacts can end up in the wrong place. Microsoft should fix the problem. In the meantime, a PowerShell script illustrates the issue and shows how a fix might work. https://office365itpros.com/2026/08/25/teams-meeting-transfer/How to Use JSON Batching to Permanently Remove Mailbox Items
Following up on the primer explaining how to use JSON batching, this article expands on the principles explored in the primer and explains how to permanently remove batches of mailbox items. Removing mailbox items requires more care and attention than updating some Entra ID user accounts, and we explain what the batch commands are to effect both permanent and recoverable deletions. A full working script is available for you to try out. https://office365itpros.com/2026/08/17/json-batching-mailbox-items/How to Bulk Transfer Meeting Ownership Between Mailboxes
The Invoke-ChangeMeetingOrganizer cmdlet can transfer meeting ownership from one user to another. In this article, we discuss using a PowerShell script to transfer meetings in bulk between users. The code requires a mixture of Exchange Online and the Microsoft Graph using a registered Entra ID app. It all sounds complicated, but really isn’t – and the code handles scenarios like transferring meetings from someone leaving the organization. https://office365itpros.com/2026/08/10/invoke-changemeetingorganizer-bulk/Use the Invoke-ChangeMeetingOrganizer Cmdlet to Transfer Meeting Ownership
The Invoke-ChangeMeetingOrganizer cmdlet transfers meetings from one organizer to another and makes sure that all calendar settings are preserved. All of which sounds good, but some limitations exist that you should be aware of. The most important limitation is that although Exchange Online can switch ownership for a meeting event, it does nothing to update any online component, like a Teams meeting join URL. That remains a manual task. https://office365itpros.com/2026/08/06/invoke-changemeetingorganizer/
Google Workspace sender stuck at SCL=5 to all Microsoft-hosted recipients
Sending email from a new domain via Google Workspace. All mail to Microsoft-hosted recipients (both Outlook.com consumer accounts and Microsoft 365 Exchange Online tenants) is being routed to junk. Authentication passes perfectly on every message. This appears to be a domain reputation cold-start issue and I am looking for guidance on how to resolve it without waiting 2-4 weeks. Affected recipients are all Microsoft-hosted recipients tested (Outlook.com consumer + Microsoft 365 Exchange Online tenants). Please help me!!! Confirmed via X-MS-Exchange-Organization-SCL: 5 and delivery header dest:J;OFR:SpamFilterAuthJ;RF:JunkEmail on all test emails including ones with normal subject lines and body text.

Techcommunity Follow email notification no longer working
Hello, Not sure if this is the right place to post this issue but I could not find another method to report this issue.. As an Exchange Admin in our invironment it's very usefull to stay up to date on the latest new posted in a variety of blogs on this website (Exchange Blog, M365 Blog, ...) This all went well until a few months ago where I started noticing I didn't receive any weekly updates anymore regarding new blogposts & tried to manually go check periodically, thinking it would be a temporary system. After investigation i've noticed that i'm not the only admin in our company that no longer receives these emails from mailto:email address removed for privacy reasons So I wonder if something bigger is up or if it's only my company being affected, not receiving these follow notifications anymore? Is there any other way that I should report this issue, to those managing this website so it can be investigated in detail if it's only us? Already tried to unfollow/delete follows in my profile - save - follow again, same on the respective blog pages, but this does not seem to change anything.Decommission from one tenant to become separate tenant

How to route emails to the new tenant (child)? Please guide.
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.
