Sharing Violations

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 contacted Microsoft Support yesterday and worked with 2nd level support who determined that the problem is within the 16.30 update and they have opened a ticket to the Excel Developers who will be contacting me later this week.

    The problem occurs when the default Excel icon is changed (performed within Get info).

    Thanks for your help...

    Hi jacsdad,

    I have the same problem with Excel.

    Can you kindly write the solution after Microsoft has contacted you?

    I had the exact same problem with Mojave after the 16.3 update. I could not save a file anywhere... local drive or network drive. Same error messages. Reverting back to 16.29 fixed the problem.
