Having the same problem here. Yesterday noticed an error icon next to my exchange account in apple mail. Deleted the account, rebooted and tried re-adding. Same error as everyone else is getting after confirming 2FA. Account is working as normal on iPad and iPhone.
The operation couldn’t be completed. (com.apple.accounts error 3.)
unable to add exchange account to the mail app on osx
