    Welcome to our forum. Everyone here has Exchange problems, so make sure you pick a better topic for your next thread. Failing to do so will result in your account being suspended for 2 weeks.

    As for your question -

    Since the Exchange server "thinks" that it is authoritative for that domain, it NDRs when you send to the other users. This is called a split SMTP domain name, and you shouldn't use Exchange in this way, but if you must, you can configure the SMTP VS to send all unresolved email to an external server, in this case - the ISPs server. However, it it not recommended to work in this manner.
