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.
I am now having the same issues. Was working fine since upgrading to Big Sur but only in last 24 hours all incoming email stopped and I have to quit and restart Mail to get new mail to come in and even then it's a one time thing. I've deleted the Exchange account and have re-added but it's not synching past 1,072 emails....and there's 70K emails in the inbox. Though large number, never been an issue before. I hate Outlook but am now trying to see if that works. Mail has been the best mail client I feel I've used and discouraged to keep having issues come back as this is not the first time. Will monitor here to see if any solutions come up. But for now, going to see if synching over the weekend helps while I use the crappy Outlook.
Thanks. I updated for Big Sur 11.1 to Big Sur 11.2 and for the time being Mail seem to work fine with the Exchange account. Mail keep coming in without me having to restart Mail to receive new mails.
Guess Mail had an issue they fixed. Keeping my fingers crossed that it stays this way.
A short and sad update.
As of today Mail is not fetching / showing any new mails on the account. I had to restart Mail again.
I experienced this problem only in the last couple of days. I decided to clean out some old emails and removed some unused folders etc. The only other thing was a MacOS security update, but I'm convinced that it was playing around with old emails and the resultant rebuilding of indexes within Mac mail that created the problem. I have no problem with the non-exchange accounts I have, nor with the same mails on iOS. It's just the MacOS Mail App. Like others Outlook works. FWIW my Exchange email reports as only being a bit under 1.0 Gbyte which Outlook agrees so I don't think this is about file sizes. I'm on Catalina 10.15.7 but its obviously not just Catalina.
Allan2021 Okay so I was intending to upgrade to Big Sur and just did it. It seems to have fixed the email problem for now, but I noted that this did not stick for others. I'm on Big Sur 11.2 now. Fingers crossed. I think that the fact that an upgrade within the local machine fixes the problem, even if only temporary for some, points the finger towards something on the Apple side of things.
