Word documents in SharePoint remain locked for longer than before after use

Common causes and supported actions for Word documents in SharePoint staying locked longer are:

1. Another user still has the file open or the file is checked out.
   • In the SharePoint document library, locate the file.
   • Point to the file to see whether it is checked out and who has it checked out.
   • If someone else is editing it, wait for them to close it or ask them to check it in.
2. A previous app session or crash left the file lock in place.
   • Close Word.
   • Restart the computer.
   • This can release a temporary lock that remains after the app stopped responding.
3. Word still has a local owner/lock file.
   • Confirm no one else has the document open.
   • Quit all instances of Word in Task Manager by ending Winword.exe.
   • In File Explorer, browse to the folder that contains the document.
   • Delete the owner file that starts with ~$ and matches the document name.
   • Reopen Word and then open the document.
4. Local Office cache is keeping stale lock information.
   • This is especially relevant if files continue to appear locked after prior SharePoint or co-authoring issues.
   • Check for pending files in Office Upload Center.
   • Close all Office apps.
   • Exit OneDrive.
   • In Task Manager, end these processes if running: MsoSync, CsiSyncClient, MsoUC, Groove, Lync, OneDrive.
   • Go to %SystemDrive%\Users\%UserName%\AppData\Local\Microsoft\Office\16.0\OfficeFileCache.
   • Rename the cache folder, then restart OneDrive and Office apps.
   • Warning: this causes loss of unsynced local changes, so save local copies of pending files first.
5. A workflow or process is trying to act on a file while SharePoint still considers it in use.
   • If a process moves or updates the file immediately after editing or approval, add a delay before the next action.
   • Configure retry behavior on the action that fails because of the temporary lock.
   • If the document is still open in the browser, close it before the workflow continues.

If the issue is specifically that locks now persist after editing even when no one is using the file, the most relevant remediation from the available guidance is to clear the local Office file cache and verify the file is not still checked out or held by another Word session.
