Mac Mail - Outlook Exchange issues
Well, for whatever its worth it just went back to working again. Not sure if it was a Microsoft issue or an Apple issue but Exchange account/Mac Mail - Catalina is working just fine again.
commanderclif Just for additional information - I'm still running Mojave, and this is now the second time I've been bitten by this. The first time was 2 days of trying things and googling for solutions - and then overnight it suddenly worked again. This time not even restarting the Mail app can be counted on for restoring functionality. My gmail account still works as well as ever, so it is definitely an Apple<->Microsoft issue, and not just Apple or just Microsoft. And since it's a joint issue both companies are telling you it's the other, and we, the users, appear to be SOL.
