I'm having a weird issue with my Outlook, 365, Exchange account in Mac Mail. This only started being a problem in the last two day. My inbox won't refresh. New messages don't come in. Messages filed or deleted on another Mac or iPhone do not move/remove. The only way I can get the Inbox to fresh to match my other devices, including the browser window version is to go Rebuild under the Messages menu in Mac Mail. I can send just fine. Clicking in to folders seems just fine as far as showing and matching what is inside. Its JUST a problem with the Inbox never updating without support.
The Mac Pro having the problem is on 10.15.7. My MacBook Pro Late 2019 running the same OS was having the problem all day yesterday but it has since be updated to Big Sur and now is working correctly. So seems to only be a Catalina issue but I'm nearly 100% sure it was a problem before I updated the Mac Pro to 10.15.7 yesterday.
I need to hold off on updating the Pro to Big Sur just yet so hoping to get a fix until then.
