Howdy -- it looks like the issue is that Dovecot is rejecting plaintext logins.

One option would be to connect using a secure method, such as using SSL/TLS option in Outlook. That would be the recommended method, and is the most secure.

Alternatively, if you prefer, we could change Dovecot to allow the insecure plaintext authentication.

Do you have a preference?
