I have a user who is trying to open a Excel file and gets a error popup that says "The server copy of this document has been updated. Your changes conflict with changes made to the server copy. Save the file somewhere else". She is not uploading the file, she is just opening it. I cleared the Office upload center cache files. Signed out of Office and signed back in. Recycled the server. Nothing helped. Even if this file is saved locally and then opened, she still experiences the same error.
Any help with this is much appreciated
