We have a small Server 2003 domain and Exchange 2003. Added a Server 2008 with Exchange 2007 to the domain, installed certificate, and migrated users to the new server. Everything works fine in house, OWA works fine, and we send and receive emails without problems. The problem is connecting Outlook and Mobile devices to the server from the outside world. We are getting one event log with the ID: 12014. Have follow the recommendations on this event and the problem still remains. However, the best that I can tell this is not cause of our problem with remote client connectivity. Outside of the STARTTTLS error everything else appears to be in order. Looking for suggestions on how to proceed troubleshooting this problem.
