Exchange 2003 -> RPC over HTTP
 

Has anyone got any ideas why this isn't working?

In the documentation when accessing https://server/rpc I should get this error:
"403.2 - Forbidden: Read access denied". That shows that the proxy is working correctly.
But after accepting the certificate and trying to log in the server won't accept my user/pass and instead I get this error:
403.1 - You are not authorized to view this page
You do not have permission to view this directory or page due to the access
control list (ACL) that is configured for this resource on the Web server.

And Outlook will still only connect via tcp/ip

How do I modify an ACL? I believe it has something to do with active directory permissions

Thanks
