mail application crash

On my Mac, I use macOS Big Sur and the Mail app, where I have an Exchange account and an IMAP account. Unfortunately, the Mail app keeps crashing. I turn on Mail, which crashes within 20 seconds of opening it and like this over and over again. I have tried to address this with Apple support but their response is just a misconfigured Exchange server which is nonsense. Other clients work on Mac, but again they are extremely taxing on the processor and battery - when I asked Apple about this they said don't use Outlook, use our Mail app. But I can't get Mail to work.


Could someone read the log what's the problem? My guess is that it's some mail message in the mailbox that's causing the crash. I've shortened the log here in the post because of its size.

About the only person that can decipher a crash log is the person that was involved in writing the code that crashed.


I have seen where a particular message will cause it to crash. Start Mail while holding down the shift key. That should start Mail without selecting a mailbox. You can then try selecting a mailbox, then the messages in it to see if one message causes it to crash.
