Question : How do I change the external OWA URL in Exchange 2007?

I am trying to setup OWA in Exchange 2007. I have the internal URL working just fine, but have ran into trouble with the external URL.

I have created an A record and can ping the name I have plugged into the external URL field in the Management Console, so I know all DNS is working properly. I have also allowed access through the firewall.

However, I still cannot open the webpage via the external URL.

What is the proper way of changing the external URL? After I installed Exchange 2007, I changed the external URL to reflect a more proper name. I wasn't sure if I needed to make any changes within IIS or not.

Any ideas?

Are you defintely still putting /owa on the end of the URL?  If OWA works internally, you definitely should not see that error, as long as you are going to the same directory on the same server.
