How to Fix AutoSave Disabled for SharePoint Files Opened from Windows Explorer
Product

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.
Before you start

Ensure your computer has an active internet connection and that the OneDrive desktop application is running, up to date, and currently syncing.

Solution 1Recommended

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Enabling the specific Office file sync setting in OneDrive and clearing outdated credentials is the most effective way to restore cloud document recognition.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.

1
Enable Office sync in OneDrive

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'.

2
Clear Windows credentials

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'.

3
Unlink and relink your account

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.

4
Restart your computer

Reboot your computer to ensure all credential clearances and sync settings take effect completely.

Adjust OneDrive Sync Settings and Clear Credentials
Sync Restored: Once your PC restarts, opening the SharePoint file from Windows Explorer should now properly trigger Office's cloud recognition and enable AutoSave.

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 This is often caused by outdated login credentials in Windows or incorrect OneDrive sync settings.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.
