PSOFT has recommended you recreate this email accounts. That would reset its settings.. could you give it a try?
Also, what I recommend is that both of you create a dummy email account with the same domain... add that to outlook as POP3. Before sending an email, POP3 with that account and you'll not face this problem...
SMTP auth is working fine from our testing
