A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
The exact text of the error is: "<filename> is currently in use. Try again later."
It happens with multiple files. None of them are shared workbooks.
It doesn't appear to happen when I choose "Save As...", even if I'm overwriting the same file.
It seems to be isolated to one network location. I've saved one of the files to other locations and I could no-longer duplicate the problem.
