We have SBS 2003R2 installed and working perfectly. Previously win Vista
client and Outlook 2003, I could use outlook anywhere without problem with
self-signed certificate.

I recently started using Win7 with a clean install on the client with OL
2003 (Office 2003) and the same SBS 2003 R2 box. Nothing has been changed on
the SBS box.

But I hv been unable to use OL RPC/HTTP from the Win7 client now.
With Exchange Remote Connectivyt Analyser to test the RPC connectiviy, it
fail with the error "The Certificate chain did not end in a trusted root"

Is there anyway, you can make Win7 use self-signed certificates to connect
OL 2003 to SBS 2003 over RPC/HTTP?
