Office for Mac no longer recognizes OneDrive files for AutoSave – “Saved on My Mac”

Since a few days, Word and PowerPoint on my Mac no longer automatically save files to OneDrive.

My files are stored in my company's OneDrive folder and OneDrive itself appears to be working normally. The files sync correctly between my Mac and OneDrive.

However, when I open a Word or PowerPoint file, Office shows “Saved on My Mac” and the AutoSave toggle is OFF.

If I manually switch AutoSave on, Office tells me that I need to save/upload the file to OneDrive. I can do this successfully, but after I close the file and open it again, AutoSave is OFF again and the file once again shows “Saved on My Mac.”

Details

macOS

Microsoft Office/PowerPoint version: 16.111

OneDrive version: 26.134.0713

OneDrive is a business/company account

Files are stored under: ~/Library/CloudStorage/OneDrive-BUSINESSNAME/

  • Example file: ~/Library/CloudStorage/OneDrive-BUSINESSNAME/FILENAME.pptx

Troubleshooting already tried

OneDrive appears to be syncing normally; there are no general sync problems.

I always open the files directly from the OneDrive folder in Finder.

I also tried opening the same files through PowerPoint → File → Open → OneDrive. AutoSave is still OFF.

I tested with a newly created presentation, not just existing files. After saving it to OneDrive, closing and reopening it also results in AutoSave being OFF.

I signed out of my business Microsoft account in Office and signed in again. The problem persists.

I checked for Office updates, but Office reports that 16.111 is up to date.

This makes it seem like Office is no longer recognizing files in my OneDrive folder as OneDrive/cloud files, even though OneDrive itself is syncing them correctly.

Is there a known issue or a way to reset the Office ↔ OneDrive integration without reinstalling/resetting the entire OneDrive setup?

    Hi everyone,

    I have been experiencing this issue on several Macs for the past few weeks.

    The following versions are currently installed:

    macOS Tahoe 26.6.2

OneDrive 26.153.0809

Office 16.112.3

    I noticed that the user's OneDrive folders (Desktop and Documents) were working correctly. However, SharePoint libraries are affected by the issue described in this discussion.

    As a temporary workaround, I removed all SharePoint libraries from OneDrive. I then went to the Documents section of each SharePoint library and selected "Add shortcut to OneDrive."

    You can choose between adding the library as a folder or as a shortcut. In my case, I preferred using the shortcut, but both options worked.

    Once added, the SharePoint libraries will be available in OneDrive either directly as folders or, if you choose the shortcut option, under the "Shortcuts" folder in OneDrive.

    This workaround has been working reliably for me so far.

    My current assumption is that this issue may be related to the rollout of Azure regions or changes on the backend, rather than being a problem with the OneDrive client itself. However, this is only a hypothesis and would need to be confirmed.

    I can also confirm the findings reported by **Antonio Valle
    **Changing OneDrive from a localized folder name (OneDrive-Persönlich) to the English folder name (OneDrive-Personal) appears to resolve the issue in my environment as well.

    What helped temporarily:

    1. Unlink OneDrive
    2. Run ResetOneDriveAppStandalone.command
    3. Re-link OneDrive

    Result:

    • AutoSave worked again
    • Files synchronized correctly again

    However, after a reboot the issue returned:

    • Office showed "Saved on My Mac"
    • AutoSave was disabled

    What finally appears to make a difference:

    I changed the OneDrive application language from German to English. This changed the synchronized root folder name from:

    OneDrive-Persönlich

    to:

    OneDrive-Personal

    After re-linking OneDrive with the English configuration:

    • AutoSave remained enabled
    • Files were recognized as stored in OneDrive
    • Synchronization worked correctly
    • Most importantly, the behavior persisted after reboot

    I have the same issue. Was on PTO during summer, so i did not notice until early september. I tried uninstalling both ONe drive and Office 365, resetting completely One drive, disconnect/reconnect, the whoe package. Nothing worked.

    Interestingly, a roll back to a previous version from June 2026 did not solve the issue.

    We are experiencing exactly the same issue on my Mac.

    I have already tried all the solutions described in this thread, including:

    • Reinstalling Microsoft 365 applications;
    • Reinstalling OneDrive;
    • Signing out and back into Office;
    • Removing Microsoft credentials from Keychain Access;
    • Resetting Office settings;
    • Restarting the Mac.

    Unfortunately, the issue remains unresolved.

    The main problem is that when I open Office files directly from the Finder, even though they are stored in OneDrive for Business and synchronization is working correctly, Excel, Word and PowerPoint do not consistently recognize them as cloud files. As a result, AutoSave and Version History are unavailable.

    At the moment, my temporary workaround is to open Excel, Word or PowerPoint first and then open the file through the application's Open menu, SharePoint or OneDrive locations. When I do this, the file is correctly recognized as a cloud document and AutoSave works normally.

    My current environment is:

    • macOS Tahoe 26.6.2
    • Microsoft Excel for Mac Version 16.112.2 (Build 26082125)
    • Microsoft 365 Business account
    • OneDrive for Business Version 26.145.0728 (26145.0728.0011)

    Is anyone still experiencing this issue with similar versions?

    Has anyone found an alternative solution or a permanent fix?

    Any additional suggestions would be greatly appreciated.

    Thank you.We are experiencing exactly the same issue on my Mac.

    Dear Carina, 

    Your testing has been very thorough, and it does point away from a normal sync failure. Because the issue affects both existing and newly created files, including those opened through File > Open > OneDrive, it appears Office is losing the cloud-file identity supplied by OneDrive rather than simply using a stale Finder path. As a forum moderator, I genuinely wish I could directly access your account or delve into the backend systems to diagnose and fix this for you. Unfortunately, my role here is limited to providing general guidance and solutions that can be applied by users. Since you asked whether there is a way to reset the Office and OneDrive integration without reinstalling everything, there are two things worth trying that are not covered by the steps you have already taken.

    1.Reset Office's cached identity and licensing.

    Signing out within Office does not always clear the underlying cached identity on macOS. To do this properly:

    1. Quit all Office applications with Command + Q.
    2. Open Keychain Access (Finder > Applications > Utilities).
    3. Search for and delete any entries containing MicrosoftOffice, Microsoft Office Identities, ADAL, and Office 365.
    4. In Finder, press Command + Shift + G and go to ~/Library/Group Containers/UBF8T346G9.Office/Licenses, then delete the contents of that folder.
    5. Restart your Mac, open PowerPoint, and sign back in with your business account.

    2.Reset the Office app container.

    A corrupted preferences container can also cause Office to misidentify file locations:

    1. Quit all Office applications.
    2. In Finder, press Command + Shift + G and go to ~/Library/Containers/.
    3. Move com.microsoft.Powerpoint and com.microsoft.Word to your Desktop rather than deleting them, so you can restore them if needed.
    4. Restart your Mac and reopen the apps.

    If neither of these resolves it, this would need investigation from the service side. I recommend that the Global Admin in your organization create a service request with Microsoft Support. A technical support engineer can perform a remote session to investigate the situation, verify the backend configurations, and run any necessary synchronization tools to resolve the problem. If the issue requires further attention, they can escalate it to a specialized team for deeper analysis. For detailed instructions on how to get support, please refer to Get support - Microsoft 365 admin. If you don't know who your IT administrator is, please refer to this article: How do I find my Microsoft 365 admin? - Microsoft Support 

    For additional assistance, use this link to find the appropriate contact number from your region: Contact Microsoft customer support | Microsoft Support 

    I truly hope you get your issue resolved swiftly. Please know that even though I can't directly intervene, directing you to the correct, specialized support is the most effective help I can provide from my position. Thank you for your patience and understanding. Please let me know if you need anything else. Wishing you all the best.
