Outlook 2003 error when connecting to Exchange 2003 server

I'm trying to diagnose issues with an Exchange 2003 server running on a
Windows 2003 box. I set up an Outlook2003 client on the server(it is a test
server). The client can send and receive but the send and receive error
comes up even though the messages are getting through - Task 'Microsoft
Exchange Server" reported error (0x8004010F): 'The operation failed. An
object could not be found.'
