OneDrive files opened from Finder not recognized as cloud files on Mac
Office for Mac: OneDrive files opened from Finder no longer recognized as cloud files – AutoSave disabled Hi everyone, I am experiencing a persistent issue with Microsoft 365 for Mac and OneDrive that started suddenly around August 10, 2026. The same setup and workflow had worked without problems for more than two years before that. Problem My Office files are stored in OneDrive and synchronized to my Mac via the standard macOS File Provider. When I open an Excel or Word file by double-clicking it in Finder, the Office application opens the file, but it apparently does not recognize it correctly as a OneDrive/cloud file. For example: AutoSave is disabled real-time co-authoring does not work as expected when I try to enable AutoSave manually, Office behaves as if the file were local and asks me to upload/save it to OneDrive – even though the file is already stored and synchronized in OneDrive However, if I open the exact same file from within Excel or Word via the OneDrive/Online Locations option, everything works correctly: AutoSave is enabled immediately co-authoring works changes made by another user appear in real time This behavior is reproducible with multiple files and affects both Excel and Word, so it does not appear to be an issue with one particular workbook or application. Environment MacBook Air M2 current macOS version current Microsoft 365 version current OneDrive version OneDrive Personal files synchronized through the standard macOS File Provider I have also tested opening files directly from: ~/Library/CloudStorage/OneDrive/... The result is the same: when opened from Finder, Office does not appear to recognize the file correctly as a cloud file and AutoSave remains disabled. Troubleshooting already performed I have already: completely reset and reconfigured OneDrive allowed OneDrive to fully resynchronize verified the files and folders in OneDrive on the web confirmed that OneDrive reports everything as synchronized restarted Finder and macOS removed and recreated Finder shortcuts/favorites tested without Finder favorites or aliases tested directly from ~/Library/CloudStorage/OneDrive updated macOS updated all Microsoft 365 applications updated OneDrive None of these steps changed the behavior. Key diagnostic result The following comparison is consistently reproducible: Finder → OneDrive file → double-click → Excel/Word → AutoSave OFF → file appears not to be recognized as an active OneDrive cloud document → co-authoring does not work correctly Excel/Word → Open → OneDrive/Online Locations → same file → AutoSave ON immediately → cloud functionality works → co-authoring works correctly This suggests that OneDrive synchronization itself is functioning correctly. The issue seems specifically related to the handoff between macOS Finder / Apple File Provider / OneDrive and Microsoft 365 for Mac when a OneDrive file is opened from Finder. Important detail This is not a workflow that has never worked on macOS. For more than two years, we routinely opened our synchronized OneDrive Word and Excel files directly from Finder. Office recognized them as cloud files, AutoSave was available, and collaborative editing worked normally. The behavior changed suddenly around August 10, 2026, without us intentionally changing the OneDrive folder structure or our workflow. Question Has anyone else encountered this recently? In particular: Is this a known regression in Microsoft 365 for Mac, OneDrive for Mac, or their integration with Apple's File Provider? Why would Office recognize a file as a OneDrive cloud document when opened through the application's Online Locations, but not when the exact same synchronized file is opened from Finder? Is there a way to reset or repair the Microsoft 365/OneDrive cloud-file recognition or File Provider integration without resetting the entire OneDrive again? Are there any relevant logs, caches or diagnostics that could show why Office considers a Finder-opened OneDrive file to be local? Opening every document through the Office application's Online Locations is a possible workaround, but it is not a practical long-term solution when working with a larger shared folder structure in Finder. I have already contacted both Apple Support and Microsoft Support. Apple referred me to Microsoft, and Microsoft Support subsequently recommended that I raise the issue here in the Tech Community. Any insight from Microsoft staff, MVPs or others familiar with Microsoft 365 for Mac, OneDrive and the macOS File Provider would be greatly appreciated.
Standardized succession planning process in Microsoft 365?
This might be a bit out there but I'm looking to build a succession planning system in our organization. Is there any way I can pull role information from Entra ID and automatically send out succession plan forms based on the individuals tenure so they can name successors? Possibly also create an attribute for potential successors for each role?File Sharing between licensed account holders
From a starting point of this year, we have been finding that any to most file shares that happened between licensed MS account users are being flagged and quarantined by the anti-malware policy. This should be, we are looking to resolve this issue. Has anyone else experienced this issue and what was your resolve. At the moment we have to monitor the quarantines and manually go in to release the share notifications.
Bookings 2026, Cannot Find or Edit "Staff" Configs
Whenever a staff member goes to bookings, they can share their 15- and 30-minute times, but they do not see Staff or anything on the left side of the window like if the menus were available. I am a global admin and even I don't see those left pane options. We made a user the Virtual Visits Admin and they also don't see those options. So how do we get Bookings to consider other calendar appointments already in place so there is no double booking? There is also not a three lines icon to open the pane to see the left side menus.Microsoft Teams and Authenticator lockdown
I’m having a very frustrating issue with Microsoft Teams. I am able to log in to teams using my normal personal email and account ONLY ON THE WEB BROWSER. From the web browser, I am not able to access the business channel that I am in. When attempting to log in on the downloaded mobile Teams App, I am sent directly to Microsoft Authenticator, which after waiting several hours, waiting even a full day, is still displaying a message about repeated verification attempt and to wait and try again later. I have accessed Microsoft support chat and they had no help for me. I need the authenticator lockdown to refresh and it will not.

Tracking whether managers actually complete their review cycles on time
Every quarter our HR team has to chase managers who havent finished their performance reviews. Right now they literally track it in an Excel spreadsheet and send reminder emails manually. Its embarrassing honestly. We're an M365 shop and I feel like there should be a way to automate this or at least get some visibility into completion rates without it being a manual process. Whats everyone else doing?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.New Entra ID group device criteria scoping is missing from Cloud Update

How can specific users be exempted from a tenant-scoped Microsoft 365 Apps Policy?
Hello, I am looking for guidance regarding Microsoft 365 Apps Cloud Policy Service behavior and policy precedence. Current configuration: In Microsoft 365 Apps Admin Center → Policy Management (config.office.com), we have the following policies: Policy 1 Name: Shorten Meeting Global Scope: Tenant Priority: 0 Configured settings: Shorten appointments and meetings = Enabled Reduce the end time of short appointments and meetings = 5 minutes Reduce the end time of long appointments and meetings = 10 minutes Policy 2 Name: Test Scope: User (Security Group) Priority: 1 Assigned only to a dedicated test group Relevant settings configured as Not Configured Observed client behavior: On corporate-managed devices, affected users receive the following registry values: HKCU\Software\Policies\Microsoft\Cloud\Office\16.0\Outlook\Options\Calendar shortenevents = End_Early endearlyshort = 5 endearlylong = 10 The Outlook option: File > Options > Calendar > Shorten appointments and meetings is greyed out. Additional validation: Using the same Microsoft 365 account on an external non-corporate device: The above registry path is not present. The Outlook option is editable. Testing performed: A user-scoped Cloud Policy was created and assigned to a dedicated security group. For the "Shorten appointments and meetings" setting, only the following options are available: Enabled Not Configured There is no Disabled option. but the Tenant policy continued to apply and the Outlook option remained locked. Questions Is there a supported way to exempt specific users from a tenant-scoped Microsoft 365 Apps Cloud Policy when the setting only supports "Enabled" and "Not Configured" and does not provide a "Disabled" option? Does Not Configured in a User-scoped policy allow evaluation to continue to the lower-priority Tenant policy? If policy precedence is changed so that: Test Policy = Priority 0 Tenant Policy = Priority 1 would the User policy potentially suppress the Tenant setting? Is there a supported way in Microsoft 365 Apps Cloud Policy Service to provide exceptions for specific users while keeping the Tenant policy as the organizational default? Has anyone successfully implemented an exclusion or override scenario for the "Shorten appointments and meetings" setting? Any guidance or documentation references would be greatly appreciated. Thank you.
