Dear,

Did you run enable-outlookanywhere on the Exchange 2007 CAS Server? Did you install the RPC Proxy components ?

Are you running Windows Server 2008 or 2003 ?

Are you offloading SSL on your reverse proxy/firewall server? What kind of reverse proxy/firewall server are you using?

What's the authentication methos you configured when enabling Outlook Anywhere? How did you configure your Outlook Client ?

Let us know a little more of your configuration so that we can help you troubleshoot....
