Inbound emails sent to users on my exchange 5.5 server are being returned to the sender with an unknown user. Can anyone tell me why this is happening?

I assume this is only internet emails from outside your organization and you have double checked the email addresses for errors. Try to send a message to echo@psi.net, it should automatically return a reply. If you are not getting a reply, check theMX records on your DNS server and your ISP's DNS server.
