How To Configure Advisor Mail when Switching Hosted Mail Providers

We are using AdvisorMail (LiveOffice) for email compliance journaling.  We are moving mail providers, going from one cloud hosted Exchange provider (Intermedia) to another (Office 365).  I have read through the 'UserGuide' twice for AdvisorMail but do not see any instructions how to intially configure it with a mail server.  Can anyone advise please?
