Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
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.
