I installed Mac OS Catalina and now all of my Microsoft Office items such as excel, word and power point do not work
None of my microsoft apps work after installing OS Catalina.
MacBook Pro 15", macOS 10.15
Microsoft Office 2016 (updated), Office 2019, and Office 365 all work with Catalina. Older 32 bit versions of Office do not work with Catalina. You need to upgrade your Microsoft Office product to a version that works with Catalina.
