Since upgrading to Catalina 10.15.1, I can't open ANY of my Microsoft 365 documents!

Ever since I upgraded to Catalina 10.15.1 today, I can't open ANY of my Microsoft 365 documents, whether they be Word documents or Excel spreadsheets. Every time I try to open them I get the message that "The document..... couldn't be opened". It is driving me nuts!!

See the replies in this topic: Microsoft Office 365 not working since update to Catalina.


One user reported that uninstalling and reinstalling office got the apps working again.
