MS Outlook connection with Exchange 2003

[Jhong]

Im trying to set up an email in outlook 2007 with ms exchange 2003. Under the exchange proxy settings, i set the connection settings to RPC.domain, and check the box that says "Only connect to proxy servers that have this principal in their certificate: I use the "msstd:rpc.domain

Sorrry, I accidently posted before i was finished. but I get an error message saying "the connection to ms exchange is unavailable. Outlook must be online or conncected to complete this action. Can anyone help me with this. Much appreciated.
