Also running with Parallels Desktop:
I would appreciate some assistance with an unusual problem involving Excel for Mac 2021 and possibly with Mac OS X, Excel for Windows 365, iCloud, and OneDrive. I generally create, edit, and save my workbooks using Excel for Mac and Excel for Windows 365 on the same file and never had any problem.
After making edits to a workbook, I tried to save the file in Excel for Mac 2021. A message appeared saying that it could not save it due to some sharing violation. It did not specify the message's source, nor a directory path or the enclosing directory name to help locate the file. Instead, it instructed me to close the workbook without saving it and to access a file named 3E0CF950.MACTF, rename it and save it as a regular Excel file.
Microsoft technical support instructed me to search at:
But the was no AutoRecovery directory. I also searched unsuccessfully on iCloud Drive and OneDrive, where I have autosave enabled when I edit my workbooks in Windows 10. I have also searched for it using Spotlight and the FIND command of the Finder with hidden files made visible. Nada.
Although Microsoft tech support thinks that the file does not exist, however, I think it's unlikely that I would get a message so detailed to include the filename if none was created.
A similar issue happened about a year ago before I had Excel for Windows installed. I was never able to find a resolution for it. Has anyone else experienced this?
Before giving up, would anyone happen to know:
Your kind assistance would be much appreciated. Please advise.

I, unfortunately, also just faced this same issue. I was working on an excel file and went to see but was told there was and "error saving and a temporary file 'EA8DAA70.MACTF' was made. Rename it and open with excel" couldn't find it anywhere. I went to terminal and wrote: "open $TMPDIR" this was sending me to the temporary files but still found nothing. I saw a post from the Microsoft team saying they don't know about .MACTF and to contact Apple support. Apple support just went through the same things I did and nothing was found.
If you had any luck, or if anyone else knows what to do let me know.

@Apeterik dealing with same issue. Started with Apple Support, they're telling me "ask Microsoft." Classic finger-pointing! Not me! Not me!

@LChoiSF I have exactly the same problem. The name for the archive is
683FB360.MACTF and it's impossible to find it anywhere.

Have a quick research and seems related to permission issue
