Users that have excel files saved and synced to SharePoint libraries can't upload/modify files. This is affecting well over 200 users simultaneously. It looks to be isoloated to one sql database.

The error message typically receive states, 'we're sorry someone updated the server version with edits that conflict with yours'.

Is there a known fix for this? We've tried having users remove cache within upload center and running repair with excel but that did not work.
