I am going to try to explain this as best as I can.
We had an IT guy here who just left the company. Everything is now in my hands. He configured the Exchange server (and firewall) to allow incoming connections from users outside the network to allow for full blown Outlook profiles.
Now, this is NOT RPC over HTTP, of that I am sure. On the desktops side, all we needed to do was modify the hosts file to point to servername.domainname.com and the proper IP, of course. Once the hosts file was modified, we could create an Exchange profile the exact same way as if I were inside the network.
Now, since he lef the company, I've moved us over to a new Exchange server (still 2003). The server name changed, as did the Internal IP. However, all of the settings on the firewall remained the same (except for where each port point to, ie the internal IP) so that mail would properly flow.
Since I made this switch, I am unable to connect with the full blown outlook profiles.
Do you guys know what type of setup this is? I've search and searched. I only find information regarding RPC over HTTP. I am POSITIVE that this wasn't the prior IT guys own configuration (he's not that bright).
Any ideas? Hints?
