unkyjoe -> Undeliverable ??? (8.Oct.2003 4:22:00 PM)

Help, we are running a SBS 2003 Server, had exchange 2003 up and running just fine. Yesterday we started receiving the following error when sending out e-mail from Outlook 2003 on our desktops connecting to the 2003 Exchange Server.

There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.
<xxxxxx#5.5.0 smtp;503 This mail server requires authentication. Please check your mail client settings.>

This happens with anybody we send to.

Any ideas of where to start?

Thanks
