How to Resolve SharePoint Offline Sync Conflicts and File Version Overwrites
Question details
Understand how SharePoint handles offline synchronization conflicts, file overwrites, and version history when multiple users edit documents offline.

- Product
- Microsoft SharePoint
- Device & OS
- not provided
- Scenario
- Multiple users edit the same shared SharePoint document offline and subsequently connect to the internet to synchronize their changes.
- Observed behavior
- SharePoint synchronizes files based on the upload or connection time rather than the actual offline editing time, causing later uploads to overwrite earlier versions.
Ensure your device is connected to a stable internet network and pause any active OneDrive synchronization to prevent further data overwriting while you troubleshoot.
Recover Overwritten Files Using SharePoint Version History
Since SharePoint prioritizes the latest upload time, you can use the Version History feature to restore content from previously uploaded document versions.
When synchronization conflicts occur due to offline editing, SharePoint saves previous iterations. Accessing Version History allows you to view and restore the edits that were overwritten by a later sync.
Log in to your SharePoint Online account via a web browser and navigate to the document library containing the conflicted file.
Right-click on the affected document and select 'Version History' from the context menu.
Review the list of saved versions by date and author. Click the drop-down arrow next to the correct timestamp and select 'Restore' to make it the current version.

Resolve Sync Conflicts via the OneDrive Sync Client
Manage local synchronization errors manually by choosing which version to keep when the OneDrive client flags an offline sync conflict.

Frequently Asked Questions
Why did my offline SharePoint edits overwrite my colleague's work?
SharePoint resolves synchronization based on the upload time, not the time you made the offline edits. The system processes the latest connection, which can cause the most recent sync to overwrite earlier uploads by other users.
Does SharePoint support offline co-authoring?
No, real-time co-authoring requires an active internet connection. If multiple users edit a file offline, their changes cannot merge in real time and will result in sync conflicts or overwrites when they reconnect.
How do I stop OneDrive from syncing a specific SharePoint library?
Click the OneDrive icon in your taskbar, select the Settings gear icon, navigate to the 'Account' tab, locate the specific SharePoint library in the list, and click 'Stop sync'.
How can I merge two conflicting versions of a Word document from SharePoint?
You can download both the server version and your local offline version, open one in your word processor, and use the 'Compare' or 'Combine' feature under the 'Review' tab to merge the conflicting changes manually.
