Archive Old Teams Channel Email Files with Microsoft 365 Archive
The File-level archiving API supports any file stored in a SharePoint Online document library, including the emails sent to Teams channels and stored in folders where the email files often disappear from view, occupying valuable storage quietly and without fuss. Finding and moving the email files to Microsoft 365 Archive makes sense because it saves on storage and stops AI tools using old email to generate responses. Here’s how to archive old email files with PowerShell. https://office365itpros.com/2026/10/06/file-level-archiving-teams/
Security loophole in Private Channels?
We came across an interesting use case in our organization today. We have a Team and a private channel within that Teams team. Within the private channel a subsite was created. I am not an owner or member of the Team nor am I a member or owner of the private channel. However during creation of the subsite I was able to be invited with unique permissions to the subsite and I was successfully able to access it. After the initial creation of the subsite, our admin was not able to add or remove or effect any additional permissions on that subsite. Is this a loophole? I expected that without being a member of the private channel I would have absolutely zero access to any items associated with the private channel and site. Which has remained true (when I go to the private channel URL I get denied access) except that I do have access to this specific subsite. My instinct is that the reason permissions cannot be changed after the fact is that this is a genuine loophole and permissions weren't intended by Microsoft to be able to be granted at all on the subsite. This is due to the fact it is under the private channel and permissions should only be able to be changed via the admin UI or from the Teams application. Has anyone come across this in their work? Any guesses or explanations for why the subsite access would be initially available? Is this just genuinely a loophole in the permissions architecture?
SharePoint - Stop sharing - new behavior or new bug?
It used to be possible for a user with Contribute permission in a library to upload a file, share it, and the stop sharing it. The result of sharing the file would be that unique permisions then apply to the file. That is, it would no longer inherit permissions from its parent container. If the user then stopped sharing the file, permisisons would be reset and again inherit permissions. This behavior has very recently changed. The person with Contribute permission who shared it can no longer stop sharing it (the Stop sharing button is grayed out). Only someone with Full Control permission can stop sharing it, and if they do, permissions for all members are removed from the fiile except for the site owners group. A user reported this new behavior to me after accidentally sharing with the wrong person, and being unable to undo their mistake. Anyone else concur with my understanding of this being a new behavior?AutoSave disabled when opening SharePoint-synced files from Finder after macOS Tahoe 26.6 update
Files stored in SharePoint Online and synchronized locally through OneDrive are opened as local documents when launched from Finder. Office applications display "Saved to my Mac" and AutoSave is turned off by default. However, opening the exact same files through Word/Excel > Open > Sites, or via SharePoint "Open in Desktop App", correctly identifies them as cloud documents. In that scenario, AutoSave is enabled and collaboration/version history features work as expected. Troubleshooting already performed: OneDrive reset and re-linked SharePoint library re-synced Signed out and back into both Office and OneDrive Removed Microsoft credentials from macOS Keychain and re-authenticated Recreated local OneDrive sync relationships Verified OneDrive File Provider extensions are enabled Verified Office applications and OneDrive are fully up to date Tested with newly created files and existing files Tested "Always Keep on This Device" with no change in behavior The issue appears to be specific to the Finder-to-Office launch path after upgrading to macOS Tahoe 26.6. Before upgrading to macOS Tahoe 26.6, opening the same SharePoint-synchronized files directly from Finder correctly preserved cloud document identity and AutoSave was enabled as expected. I discussed this issue in detail with Apple Support, but they quickly dismissed it, saying that the problem is not on Apple's side and that I should contact Microsoft instead.M365 Tenant to Tenant Migration
Hi Community, One of our customer currently migrating some OneDrive DATA from their old tenant to a new one. Customer wants to keep same domain names. So they must first remove them from the old tenant to create them in the new one. But they're afraid to loose the (OneDrive) DATA associated with the accounts when they will be moved to the initial ".ONMICROSOFT.COM" domain (which will happen after domain name removal). Questions: 1. What exactly happens with the accounts of OneDrive DATA once the old domain (wherein it was originally hosted) is removed ? 2. What is the best practice in this context to retrieve any associated DATA during/after migration? They want to check the priority steps knowing that they want to keep its domain name in the new tenant, which mean they'll have to detach the domain from tenant source to create it in target tenant 3. Should they first create a temporary domain where users will be migrated to, remove the domain name from tenant source to free it and create it in target tenant, then create the users ? or can they simply remove the domain name which will cause the existing users belonging to this domain to be automatically moved the initial .ONMICROSOFT.COM domain (with all the dependencies and OneDrive Data) ? Any pointers would be of great help! Many thanks in advance!SharePoint AI innovations hit GA, powering new Copilot app and agents
SharePoint AI innovations hit GA, powering new Copilot app and agents Today we announced the new Copilot app, bringing together how people assist, delegate, build, and automate work in one experience powered by Work IQ. Because Work IQ grounds these experiences in your work and organizational context, the quality and structure of knowledge behind them matters more than ever. The better that content gets, the better Copilot gets: in Microsoft evaluations, responses in the Copilot app improved by an average of 17 percentage points when the underlying content had been enriched and structured by Copilot. That’s why over the past year we’ve invested in Copilot’s content experiences and tools – both in the Copilot app and inside the content repository itself with the Copilot in SharePoint preview. In just the past month, millions of users have tried this preview, applying it to real-world challenges to translate complex content into tangible business value and accelerate their organization’s AI transformation.Copilot, Microsoft 365 & Power Platform Community call
