Full Outlook Access From Outside the Network Exchange 2003

Hello everyone,

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?

Have you checked your network's MX and A Records?

Yes,

E-mail is flowing properly. That is not an issue. I'm thinking it has to be some kind of registry configurations as the only thing that really changed was the server itself (firewall remained the same)....

Cobra,

Thank you for the response. I've already modified the hosts files on the machines to point to the new server (public IP stayed the same, but did modify the name). Still can't connect! :(

Mestha,

You are most definitely correct. I am in your boat, I agree that it should have been RPC/HTTP a long time ago. And I do agree that it is unsafe. But I need a resolution ASAP, boss isn't ready to purchase an SSL certificate yet to make it possible (what are the costs? I don't think they're even that pricey?)

Thanks again for all of the assistance. Still hoping to come to a resolution.
