I am guessing I am behind the times a bit. In E2003 we needed to have port 80 open on the mail server for OWA.
With the E2007 I setup all the Exchange roles are housed on one physical server. That said, do we need port 80 open anymore for the E2007 server to work?
On this E2007 box We do not use Outlook Anywhere. External access is only via OWA and ActiveSync. Internal access is via MS Outlook
