AutoSave disabled when opening SharePoint-synced files from Finder after macOS Tahoe 26.6 update

Question

AutoSave disabled when opening SharePoint-synced files from Finder after macOS Tahoe 26.6 update

Batuhan Köklüçınar 35

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'm just out of ideas now how to fix this since Apple won't let me return to previous MacOS version in an easy way. That's just too much work. :(

Hi @Nicolas D

Based on the feedback link I shared earlier, one user reported that the issue was related to the use of non-English characters in the root folder name.

Could you please review the screenshot below and check whether your root folder name contains any non-English characters? If it does, please try following the mentioned steps and then test the issue again.

Es un problema con los caracteres especíales del idioma. No hace falta cambiar el idioma de la aplicación OneDrive. Lo que hay que hacer es cambiar la carpeta de OneDrive. En mi caso, de "OneDrive - Escolapios Emaús" al mismo nombre sin tilde "OneDrive - Escolapios Emaus" que estaba alojada en ~/Library/CloudStorage

Hello @Batuhan Köklüçınar,

Based on the information you provided, I understand that you are unable to use the AutoSave feature when opening locally synced files, and that the issue started after upgrading to macOS Tahoe 26.6.

As this is a relatively new macOS release, we currently do not have any known records or widespread reports of this specific issue. However, I will continue to monitor for similar cases and keep you informed if we identify a broader trend. At this stage, there is a possibility that the issue is related to a compatibility conflict between the OneDrive sync client and the new macOS version.

In the meantime, I strongly encourage you to submit your feedback through the Microsoft Feedback Portal. The Microsoft development teams actively review customer feedback, and many enhancements have been implemented based on community input. The engineering team will analyze reported cases and gather feedback from affected users to evaluate whether a future update is required to improve compatibility with the latest Apple release.

If you decide to submit feedback, please feel free to share the link with us. I would be more than happy to support it, and doing so may also help increase visibility so that other users experiencing the same situation can find and endorse it. The more engagement a request receives, the higher the likelihood that it will be carefully reviewed.

Thank you again for clearly documenting your concerns. I sincerely hope this feedback will be reviewed and upgraded by Microsoft in the near future.

Hi Helen, thanks for the prompt answer.

I've sent the feedback to MS, here's the link: https://feedbackportal.microsoft.com/feedback/idea/95d53d4a-5e92-f111-9b47-6045bd856709

And FYI, in the meantime I've also tried running Mac in Safe Mode and trying all of the steps above but still no luck. I've also had 2 different sessions with Apple Tech Support, and in both sessions they've told me that the issue is related to Microsoft apps. Apparently One Drive Finder paths are not being recognized as cloud files by Word/Excel.

Hello Batuhan,

Thank you so much for your prompt action.

In this situation, I would also recommend creating a support ticket with the Microsoft Support team so they can perform a deeper investigation and review internal resources. If necessary, they can further escalate the issue to the Microsoft engineering team for more in-depth analysis and troubleshooting.

If you are not a Microsoft 365 administrator, please reach out to your IT administrator and ask them to create a support ticket by following the instructions provided here:

Get support - Microsoft 365 admin | Microsoft Learn

Please let me know if you have any concerns or updates on this matter.

Sharing what fixed this for us (so far), in case it helps others.

We had the exact same symptom on several Macs in our organization: Office files in synced SharePoint libraries, opened from Finder, showed "Saved to my Mac" with AutoSave off, while opening them via File > Open > Sites worked fine.

We were already using the standalone OneDrive (not the App Store version). What resolved it was a complete removal and clean reinstall of OneDrive:

Quit OneDrive.
Ran the reset script from the app bundle (OneDrive.app > Show Package Contents > Contents > Resources > Reset...Standalone...command).
Moved OneDrive.app to the Trash.
Removed all remaining OneDrive-specific items in ~/Library (Application Support, Caches, Containers, Group Containers, FileProvider), the OneDrive LaunchAgents/LaunchDaemons and receipts, plus the OneDrive entries in Keychain. Careful: do NOT delete the UBF8T346G9.Office or UBF8T346G9.ms group containers, they are shared with Office.
Restarted the Mac.
Reinstalled the standalone OneDrive from Microsoft's download page (not the App Store) and re-synced the SharePoint libraries from the browser.

After this, files opened from Finder are recognized as cloud documents again and AutoSave is on.

Current setup: OneDrive standalone 26.168.0830.0006, macOS 27.0.1, Apple Silicon.

Make sure everything is uploaded before unlinking or removing OneDrive, as files that haven't synced could be lost.
