We have a document on a shared file that when "user 1" opens it, no one else can. However it appears that for some users this "exclusiveness" goes away after a period of time and someone else can open the worksheet unaware that user 1 still has it open on their desktop. This is quite frustrating
The file is on a file shared drive; We have been using the one user at a time approach. I am a bit uncomfortable with the coauthoring approach as I am unfamiliar with how it works. We are using this file to assign blend id codes for our wine lots so it is important not to have duplicates.
