>>>>>>>>>>>>>> 2) Enable the Exchange server as an RPC/HTTPS backend server.

>>>>>>>>>>>>>> HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Rpc\RpcProxy

>>>>>>>>>>>>>> The DWORD value Enabled should be set to 1

>>>>>>>>>>>>>> exch01:6001-6002;exch01:6004;exch01.contoso.com:6001-6002;exch01.contoso.com:6004
