Fix Office AutoSave Not Working on SharePoint Network Drives
Question details
Users are unable to use AutoSave or real-time collaboration features in Office applications when opening documents through mapped SharePoint network drives.

- Product
- Microsoft Office, SharePoint, OneDrive
- Device & OS
- not provided
- Scenario
- Attempting to collaboratively edit and automatically save Office documents hosted on SharePoint via a mapped network drive.
- Observed behavior
- AutoSave is disabled and real-time collaboration stops working entirely, specifically noted starting from Office version 2306.
Verify your current Microsoft Office version in the Account settings and confirm whether you are accessing the affected documents through a mapped drive letter rather than the official OneDrive sync client.
Use the OneDrive Sync Client Instead of WebDAV
Bypass the outdated WebDAV protocol by opening your SharePoint or OneDrive files directly through the modern sync client to restore collaboration features.
SharePoint WebDAV network drive mappings utilize an older access method that does not fully support modern Office AutoSave and real-time collaboration features.
Transitioning to the native OneDrive sync application ensures that Office applications can communicate properly with SharePoint servers.
Open File Explorer, right-click the mapped SharePoint drive letter, and select 'Disconnect' to remove the WebDAV connection.
Log into your Microsoft 365 account through a web browser and navigate to the SharePoint document library you need to access.
Click the 'Sync' button in the SharePoint top toolbar to connect the document library with your local OneDrive desktop application.
Open your Office files directly from the newly created SharePoint or OneDrive folder in File Explorer. AutoSave will now function normally.

Roll Back Your Microsoft Office Version
If your workflow strictly requires mapped network drives, rolling back to an older Office release like version 2302 may temporarily bypass the AutoSave bug.

Frequently Asked Questions
Why does AutoSave fail on a mapped network drive?
Mapped network drives typically use the WebDAV protocol, which is an older file access method. Modern AutoSave and real-time collaboration features require newer synchronization protocols provided by the OneDrive client, causing conflicts when WebDAV is used.
Will AutoSave work if I open files directly from the browser?
Yes. Opening files directly from the SharePoint web interface or through the official OneDrive desktop sync client fully supports AutoSave and real-time document collaboration.
Which Office versions are affected by this SharePoint network drive issue?
Users have widely reported that AutoSave on WebDAV network drives broke starting with Microsoft Office version 2306 and continues into version 2307. Rolling back to version 2302 has resolved the issue for some organizations.
How do I report this mapped drive bug to Microsoft?
You can report this directly from any Office app by clicking on 'File', selecting 'Feedback', and clicking 'Send a Frown'. Be sure to mention that the issue occurs specifically with SharePoint WebDAV mapped drives on your current Office build.
