Fix AutoSave Disabled for SharePoint Files Opened from Windows Explorer
Question details
The user is trying to resolve an issue where the AutoSave feature in Office is turned off or saves to the incorrect account when opening a SharePoint file via a synced OneDrive folder in Windows Explorer.

- Product
- Microsoft Office
- Device & OS
- Windows
- Scenario
- Opening a synced SharePoint document locally from Windows Explorer to edit with real-time AutoSave enabled.
- Observed behavior
- Office fails to recognize the file as a cloud document. AutoSave remains disabled, or the file is saved to the wrong OneDrive account rather than the designated company SharePoint library.
Ensure your computer has an active internet connection and that the OneDrive desktop application is running, up to date, and currently syncing.
Adjust OneDrive Sync Settings and Clear Credentials
Enabling the specific Office file sync setting in OneDrive and clearing outdated credentials is the most effective way to restore cloud document recognition.
When Office applications and OneDrive lose their sync communication, Office cannot verify that a locally opened file actually lives on SharePoint. Re-enabling the connection and clearing old caches forces a fresh authentication.
Click the OneDrive cloud icon in the Windows system tray, click the gear icon, and select 'Settings'. Navigate to the 'Office' tab and check the box for 'Use Office applications to sync Office files that I open'.
Open the Windows Start menu, type 'Credential Manager', and press Enter. Click on 'Windows Credentials', locate any entries related to 'MicrosoftOffice' or 'OneDrive', and click 'Remove'.
In the OneDrive Settings menu, go to the 'Account' tab and click 'Unlink this PC'. Once unlinked, sign back in using your work or school Microsoft account.
Reboot your computer to ensure all credential clearances and sync settings take effect completely.

Clear Sign-in Cache with Microsoft Support and Recovery Assistant
Use Microsoft's official utility to deeply clean the sign-in cache if manual credential clearing does not resolve the sync issue.
Perform a Clean Reinstallation of Microsoft Office
If all sync settings and credential clears fail, a clean reinstall of Office can fix deeper application corruption causing AutoSave failures.
Try WPS Office for Seamless Document Management
If Microsoft Office sync issues and AutoSave errors disrupt your workflow, consider switching to WPS Office. It is a lightweight, reliable, and user-friendly alternative that provides excellent document compatibility and robust local and cloud saving features without the complex credential errors.

Frequently Asked Questions
Why is AutoSave disabled when opening SharePoint files from Windows Explorer?
This usually happens because Microsoft Office fails to recognize the locally synced SharePoint file as a cloud document. This is often caused by outdated login credentials in Windows or incorrect OneDrive sync settings.
Can I manually force AutoSave to turn on in Office?
If the file is not properly recognized as a synced cloud document, the AutoSave toggle in the top-left corner will be grayed out. Trying to turn it on will typically prompt you to upload a new copy of the file to the cloud instead of syncing the current one.
What does the 'Use Office applications to sync Office files' setting do?
This OneDrive setting enables Office applications to co-author and share files in real-time. When it is disabled, OneDrive handles the file syncing independently in the background, which prevents the native Office AutoSave toggle from working.
Will unlinking my PC from OneDrive delete my SharePoint files?
No. Unlinking your PC only stops the active syncing process between your computer and the cloud. Your files remain safely stored on SharePoint, and any files already downloaded to your hard drive will remain there.
