Ive setup an exchange proxy front end server but I cannot get clients to
connect through the firewall. I can sucesfully connect using RPC-HTTP when
Im on the LAN, but when I fire up Outlook from home, I get a username and
password prompt but then it just sits there saying "Trying to connect" and
never actually connects.

I read MS article 833401 and have all the updates I need but theres
something Im missing here. As soon as I connect over a VPN connection,
Outlook connects fine!

Ive opened up firewall port 443 for SSL traffic to the proxy server, and
port 80 to the proxy server. Is there anything else that needs to be opened?

Can anyone offer any help on this?

Much appreciated,
Grant
