Exchange 2003 Web Mail

Have setup an Exchange 2003 Server, can access webmail from internal network, but not from outside. Is there some port in my router I need to open? I have a Web server on the same system and I can access that. Port 80 is open on the firewall too.

Drev001 and digisaur,

thank you for your responses. You were pretty close with the port forwarding train of thought but not all the correct ports.

Apparently with Exchange 2003 when you try going to the Exchange 2003 webpage it redirects to use HTTPS which requires to have port 80, 81 and 443 port forwarded to the server as well.

I have figured it out when running a netstat command while connecting to the server.

Regards to all and thank you again.

Both Ports 443 and 81 are blocked in my setup and I have no problems accessing OWE through port 80 only.

I can't see why you'd need 443 open unless you are explicitly using SSL.
