A Microsoft Project file hosted in SharePoint does not reflect recent updates and shows an older version instead.

How to Fix SharePoint Showing an Old Microsoft Project File Version

Product: SharePoint and Microsoft Project
Device & OS: not provided
Scenario: Accessing a shared Microsoft Project file from a SharePoint document library after collaborative editing.
Observed behavior: The file opens as an outdated version, failing to display the newer edits checked in by another user.

Before you start

Verify that the user who made the latest edits has fully checked the file back into SharePoint and that no server-side sync errors occurred during their upload.

Solution 1Recommended

Verify SharePoint Version History and Clear Local Cache

Confirm the updated file exists on the server and clear local cached data to force Microsoft Project to download the latest version.

Often, SharePoint properly receives the new file, but your local Office or browser cache mistakenly loads a previously saved version of the .mpp file to save bandwidth.

Check SharePoint Version History

Open your SharePoint document library in a web browser. Click the three-dot menu (...) next to the Microsoft Project file and select 'Version History'. Look for the timestamp of the latest check-in to confirm the server has the updated file.

Close Microsoft Project

Ensure the Microsoft Project desktop application is completely closed so that no background processes are locking the cached file.

Clear Office Cache

Open the Microsoft Office Upload Center (or Office Document Cache settings in newer versions) and choose to delete cached files. Alternatively, clear your web browser's cache if you are using the web interface.

Reopen the File

Navigate back to the SharePoint document library and click the Microsoft Project file to open it directly from the server, fetching the latest version.

Verify SharePoint Version History and Clear Local Cache

File Sync Restored: Clearing the cache forces the application to abandon the old local copy and pull the accurate, up-to-date version from SharePoint.

Solution 2

Test Other Files to Isolate the Synchronization Issue

Determine if the issue is specific to one corrupted Microsoft Project file or a broader SharePoint library sync problem.

Frequently Asked Questions

Why does SharePoint show an older version even though my colleague saved the file?

If a colleague merely saved the file locally but did not formally 'Check In' the file back to SharePoint, the server will not register the new version. Additionally, your local Office cache might be loading a previously downloaded version instead of fetching the latest one from the server.

How do I ensure my Microsoft Project edits are visible to others in SharePoint?

Always 'Check Out' the file before making edits. Once you are finished, you must 'Check In' the document from the SharePoint interface or the Office application prompt, optionally leaving a version comment so others can see your updates.

Can I recover an older version of my Microsoft Project file in SharePoint?

Yes. Navigate to the SharePoint document library, click the ellipses (...) next to your file, and select 'Version History'. From there, you can view, restore, or delete previous versions of the document provided that versioning is enabled on your library.

Does Microsoft Project support real-time co-authoring like Word and Excel?

Unlike Word and Excel, standard Microsoft Project (.mpp) files do not typically support real-time co-authoring in SharePoint. Files must be strictly checked out by one user at a time to prevent conflicting copies and version mismatches.
