This sounds to me like an authentication method problem. The two main authentication methods are LOGIN and PLAIN, but Dovecot only enables PLAIN by default. Outlook, however, remembers the last mechanism that worked and always tries to use that in future. Also you may be attempting to use POP without SSL, (*) which Dovecot also hinders. In my case I needed to add the following to /etc/dovecot/local.cf during a similar migration to what you described: disable_plaintext_auth = no auth_mechanisms = plain login (*) Don't EVER do this. Just because I maintain systems where this is a requirement doesn't mean I think it is a good idea.
