Using RPC/HTTP Exchange 2003. If I do https:\\mail.domain.com/rpc
on the network it returns a blank page with a link to parent directory and rpcproxy.dll.
Our OMA and OWA settings work fine using a third party trusted certificate, so I don't see why the RPC isn't working as well. We have completed all the registry edits etc.
Outlook works internally if you set it to use HTTP but I assume that is because it resolves it back to the name of the internal mail server.
