Exchange sync issues with Apple Mail app on macOS Monterey

Hi, ever since I upgraded to Monterey on my MBA, my mails (exchange) just won't sync properly in the app. They start downloading first but it stops. The Activity Monitor shows as if the download is frozen. New mails don't show up whereas it's working fine on my iPhone and iPad. However, the new mails get downloaded when I force quit the app and reopen it. Otherwise if I keep the app open, new mails stop downloading. I have tried doing the following but it hasn't worked. Is it an issue with Monterey OS that might get fixed in an upcoming OS upgrade since the Mail app was working like a charm on BigSur.

Rebuilt the mailbox
Reconfigured the mailbox by first deleting it from Internet Accounts
Tried manual IMAP and SMTP server settings
Deleted mail profile in Library
Reinstalled Monterey OS

What else can I do? Am stuck. And I don't want to use the Microsoft Outlook app for macOS. I like the native Apple Mail app.

Ok, I've finally managed to get my Mail to communicate with Exchange. I first removed my old Exchange email account and then reopened it. I noticed that under User Name it had my email address so once I changed that back to my User Name and entered server address manually. That did the trick.

Thanks, TeddyBW. I'm using Outlook on my PC instead of Apple Mail on my iMac for the messages Apple Mail can't handle.

Interestingly, the Apple Mail app on my iPhone still has no problem showing Outlook messages.

They may be de-prioritizing the Mac?

Thanks Alan, no I don’t have any antivirus. What do I have to do in SafeBoot method? What to look for specifically?

It sure is a bug. My Mail app on Monterey OS is still erratic and has a mind of its own. Starts and stops working just like that. Getting most of my mails done on microsoftonline portal. Pity!!

IVICAA's solution didn't work for me.

Please please Apple can you unbug this?

I have to guess there's lots of people who add Outlook accounts to Apple Mail!

Thanks, Justinarch. Let's hope Apple responds.

Thanks, BillyWilder. Remember when their slogan was, "It just works"? Here's hoping they'll fix the bug where their mail app doesn't work with Gmail and/or Exchange.

Dear Apple, we believe in you and know you will debug Apple Mail in Monterey.

It's been a month and Apple has not found the time to respond.

I am migrating all my email accounts to Microsoft Exchange today and I will demote Apple Mail to a secondary email account.

Thank you for your persistence Billy and for the good (if depressing) information.

Sadly, it's been a month and still no word from Apple. If the business strategy is to drive people away from MacMail and iCalendar, and to Outlook... it's working.

Hi All! Seems my Mac Mail on my MacBook Pro is now synching with Exchange mail. Calendar too.

Feb 2, 2022 6:07 PM in response to horacenalle

I have the same problems. Is the solution to delete the Exchange account and set it up again?

Feb 3, 2022 2:57 AM in response to CHruediCH

Exchange account deleted, reinstalled and is working!
