I am starting to migrate an exchange 2003 server to another exchange 2007 server. I moved a mailbox over to the exchange 2007 server and I am able to send and receive internally. I am able to receive from external email domains. But I am unable to sent or reply to external email domains, such as hotmail. I added the * in the address space for the send connector but no results.
The error received on the 2007 sender is: Expired; message expired in unreachable destination queue. Reason: A matching connector cannot be found to route the external recipient
Any help is greatly appreciated.
