Outlook RPC over HTTP

Hi

We have a SBS 2003 (no service pack), running Exchange 2k3 SP2, ISA 2000.

We are having problems configuring Outlook to Communicate with Exchange over
HTTP.

We have configured the subdomain Remote.OurDomain.co.uk to point to our
server, we have a server SSL certificate configured for
https://Remote.OurDomain.co.uk and our client has the reletive client cert,
the domain is in the Intranet Site List on the client and can browse to OWA
& remote web workplace.

I get the response "Forbidden: Read access is denied." when I goto
https://remote.ourdomain.co.uk/rpc which i hear is correct.

I have configured Outlook as below:


Exchange Server: ourserver.ourdomain.local
Username: my username

Exchange over the Internet Settings:
Checked : conect to my Exchagne mailbox using HTTP

Proxy Setttings:
URL: remote.ourdomain.co.uk
connect using ssl only: Checked
mutually authenticate the sesssion when connecting with SSL: checked
Principal Name For Proxy Server: msstd:publishing.MyDomain.local

On Fast Networks... Checked
On Slow Networks... Checked

Proxy Auth: Basic Auth


When I open outlook i get prompted for my username & password a number of
times and then it says disconnected.

Any advice would be much appreciated

Thanks
B
