Question details

AutoSave is disabled and fails to work when opening Office files from a OneDrive-synced SharePoint folder using Windows Explorer.

Product: Microsoft 365, OneDrive, SharePoint
Device & OS: Windows 11
Scenario: Opening synchronized Excel, Word, or PowerPoint files from a SharePoint folder via Windows Explorer and attempting to use AutoSave.
Observed behavior: AutoSave appears as turned off. When attempting to turn it on, the application prompts the user to save the file to the main OneDrive folder instead of the correct SharePoint location, despite standard OneDrive synchronization and manual saving working fine.

Before you start

Ensure that your OneDrive application is fully updated to the latest version and that you are signed in with the correct Microsoft 365 account linked to your organization's SharePoint.

Solution 1Recommended

Escalate to Microsoft Support via Microsoft 365 Admin Center

Since reinstalling Windows 11 and Microsoft 365 does not resolve this specific synchronization issue, administrators must contact Microsoft Support to investigate backend logs and settings.

This behavior often indicates a deeper discrepancy between the local OneDrive synchronization engine and the SharePoint backend. Microsoft Support has the specialized tools necessary to review diagnostic logs and backend account configurations.

Collect diagnostic information

Gather the affected local file paths, detail the application behavior (the specific prompt asking to save to the main OneDrive folder), and confirm the exact Windows and Office versions.

Access the Admin Center

Create a service request

Navigate to the 'Support' section on the left-hand menu and select 'Help & support' to open a new ticket detailing the SharePoint AutoSave failure.

Submit logs to Microsoft

Provide the collected details and follow the support agent's instructions to upload any required synchronization logs.

Solution 2

Request Assistance from Your IT Administrator

If you do not have Microsoft 365 administrator privileges, you will need to request that your IT department opens a support ticket on your behalf.

Frequently Asked Questions

Why does AutoSave prompt me to save a copy to my personal OneDrive instead of SharePoint?

This happens when the Office application fails to properly recognize the synchronization path of the SharePoint folder, treating the opened document as a locally stored file that needs to be moved to the cloud to enable AutoSave.

Does reinstalling Microsoft 365 fix SharePoint AutoSave issues?

While reinstalling can fix local file corruption or broken application caches, it often fails to resolve this specific AutoSave issue because the root cause typically lies in backend account configuration or synchronization engine bugs.

Can I still manually save my files to SharePoint if AutoSave is broken?

Yes. Even when AutoSave is disabled, you can save your files manually by clicking the Save icon or pressing Ctrl+S. The OneDrive sync client will continue to synchronize these manual changes back to SharePoint.
