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.
DocEames Hi, I struggled with this for years ( still do for people I support but I use Outlook) and Apple has neglected the Mail App. My current issues magically went away after I escalated with MSFT and Apple. If only they would reveal the cause we could all jump to the band-aid solution immediately and have them implement it each time instead of the support desk being totally unaware each time. It doesn't permanently won't fix the issue but would expedite the resolution each time. Outlook works because it uses a different protocol to retrieve email and if you flip the "New Outlook" switch, in outlook for MAC, it looks very much like Apple Mail. (Sorry, I had to throw that out there. ) Then just use the native apple contacts and calendar because I find Apple Mail user don't like the fact that the calendar and contacts in Outlook are a tab at the bottom of Outlook for MAC and you can't pop out the separate Windows. You do need to make changes/additions from the Outlook Calendar and contacts tab or through or your phone; I've seen issue otherwise with updates. So I recommend using the latest Outlook and uncheck Mail in the Internet settings and just ( my experience not documented anywhere ) leave Contacts and Calendar. If you are stuck on Apple Mail make sure to keep you item counts down to less then ~20K for each folder, no subfolders if you can help it and the size below 15GB. You need to rebuild from scratch each time this happens. The one off rebuild brings down the new mail but will not continue work; you have to hit rebuild every minute which is not useful. I wish I knew the root cause and I know someone at MSFT or Apple engineering does but perhaps they blame each other? ( long history their)
