I have an MS Exchange Server 2003 and use Outlook 2003 clients on Windows Server 2003.
I am able to send internal emails, but external emails are being bounced back.
I would like to simply point exchange to our ISP and have it forward the emails to the ISP for distribution.
My knowledge of Exchange is extremely limited.
Currently when I send an external mail the non-delivery report is
"The e-mail account does not exist at the organization this message was sent to."
But I know the account does exist!
Thank you for any help/advice!
