Question about viewing/editing permissions in an excel file that is shared on dropbox-
I have an excel file that is shared through dropbox but not on the actual excel file. Multiple people use this excel file to keep track of things on a spreadsheet, however, when two people are in it at once, the saves get messed up and it creates a new file where it saves for the user that edited it, but it does not save on the original file for the other users to be able to view. I'm not sure I fully understand the problem so I hope I have adequately described what I believe is going on.
Basically, I am wondering if there is a way to lock the dropbox/excel file so only one person can get into it and edit it at one time, but everyone that it is shared with still has their same permissions to be able to edit it- but only when no one else is in the file.
I hope that makes sense.
