Why are you looking for an IMAP connector for Exchange when the SBS POP3
connector will connect the mail just fine?

You should not use your FQDN as the name of your local domain. Your
internal Active Directory domain has no correlation to the FQDN and the
ability to get email.
When you run the Connect to Email and Internet Connection Wizard (CEICW) it
will make the necessary modifications to email addresses etc for your users.

DO NOT USE the FQDN, it will only cause you more issues down the road.
