Open a copy of a locked file
When I try to open a file that another user is accessing in desktop Excel, I get an error because the file is locked. If real-time coauthoring isn't supported on the desktop, it would be great of Excel Online would give me the option to open and edit a copy of the original so that the files could be combined later.
Please ad the functionality for users to edit as a copy if the file is currently open. So frustrating!
