I have this very strange problem with publishing an Exchange server behind ISAServer. I use the "Secure Mail Server" publishing wizard to publish my Exchange server. Everything works fine with respect to POP/SMTP but Outlook clients connecting to my server can only resolve their mailbox name (when they setup their profile). When they launch Outlook it fails to connect to the server. I know it can connect since it properly resolves the name and sets up the profile. David A.
