Just installed Exchange 2003 and applied SP2 on a Windows 2003 Standard server. (Single server setup) I have set this up at least 4 times before and had it work. Got an SSL cert from StartSSL and applied. Can visit OWA over HTTPS without any cert errors, but Outlook just will not work.
To avoid the easy questions, this is what I have done:
Add/Remove Programs - Windows Components - Added RPC over HTTP support
Exchange System Manager - Server properties - RPC-HTTP tab - turned on RPC-HTTP backend server
Requested a cert for my external FQDN ( and applied to RPC virtual directory (require SSL and 128bit ecrypt)
Removed anonymous access for RPC virt dir and enabled Basic Auth
Made sure server was a Global Catalog server
used RPCnoBackend tool to set registry port settings and verified manually that everything is correct.
Reboot server
Setup clients to use RPC over httpS,, basic auth
Won't Connect!!! Please help, been troubleshooting for a week now!
