Since installing Catalina 10.15 and Office 365 16.30 (updates installed the same day (something I will not due again)) when I attempt to save a workbook that I have used for a couple of years, I receive the alert: 'Your changes could not be saved to xxx.xlsx due to a sharing violation. I then receive the alert The file format end extension of 646820000.mactf don't match.
I contacted the Answer Desk who say it is an Apple Product and Apple support said it is a Microsoft problem.
Any thoughts or suggestions will be appreciated.

I continue to experience the same issue with Word 16.39. Is anyone else experiencing this problem with the newest version?

We're still having it as well, and we're on v16.39 like you. For us, it's also Excel and PowerPoint; we don't use the other apps.
