Since you can use OWA, and you probably have a firewall or router/firewall, you must be aware of having configured the firewall to pass http (port 80) or https: (port 443) traffic to the Exchange server. The reason you cannot "find" the mail server with Outlook is because that requires much more than ports 80 or 443. Don't change anything in the firewall. It's keeping your server from being the target of hackers. In fact, if you have port 80 open, you want to close that, install a certificate, and only access OWA over https/443. Now, what you are missing in Exchange is called "RPC over https". This lets you access the server with Outlook, securely, without a VPN. The requirements for this are all of the 2003 products (Windows, Exchange, Outlook) and Windows XP on the client.

As for the networking team...im it. So if I cant do it, it aint getting done.
