We have a new exchange server right now and all is working fine and well.
I have set up an external A record for the domain name 'mail.domainname.com' to point to the external IP on our firewall and that is also redirecting to the internal IP which is our Exchange server.
However, when I type this URL in to the web it goes to the IIS page, so obviously I haven't configured some sort of redirect?
How can I configure this to work correctly? is it in the IIS Manageer in the OWA virtual directory?
Thanks for helping
