Microsoft Exchange email not sync-ing after upgrade to Monterey
I have a MS Exchange email account that is active on my iPhone and my MacBook. After upgrading both devices to the latest MacOS 12 and IOS 15, I can no longer receive email on the MBP. Messages continue to arrive at the iPhone and I can send email using the Exchange account from my Mac.
I've checked that I have the same Apple ID logged in on both devices. I see no errors logged I've looked at the console log filtered on the Mail process and see numerous and frequent messages with the Exchange server - no indication of errors
