We have two servers on our LAN. One is a Windows 2003 Server domain controller running Exchange 2003. The other is a stand-alone Windows 2008 server running IIS 7. Our company website runs on the IIS 7 (2008) server, so the firewall forwards port 80 to this. How can I get OWA and ActiveSync to work with this setup? And without using SSL.
I have tried setting up a website on the IIS 7 box (mail.ourdomain.com) and using HTTP redirect to point to http://mailserver/exchange, but this doesn't work.
Do we have to purchase an SSL certificate for this to work?
