Using New Outlook on Windows for personal email, calendar, and contact management
I have 3 Microsoft 365 installations, all on Windows 11 Pro computers. On two of them, the Report button works as expected, but on the third one. I have run a couple of Online repairs, but they have not restored the Report button. Regarding your reference to a COM Add-in for the Report button, all three machines have the same COM Add-ins installed and enabled. NONE of the Add-ins are "Report Message add-in" or anything similar.
