Angelo, thank you so much for the suggestion. I gave that a try but still ended up with the same issue. Here is the log from the activity viewer:

Hello,

I’m writing to see if anyone has advice for how to troubleshoot Mailmate’s compatibility with Office365.
I had this happen in the past several times. Office365 (cloud) would work fine and then stop working suddenly. The only thing I found that would work was to completely remove the account in MailMate. Also, I had to remove the key(s) in the Apple Keychain application. Then I set it up again and it kept working (for a while).
With regards,
Angelo Machils
