I created an new exchange account, if we send emails to this address from inside the domain it works just fine, they are delivered with no problem.
if you send him an email from any address outside the domain it is returned to the user saying the delivery failed.
What Can I check in exchange to resolve this issue?
UPDATE
This is all hotmail tells me when it returns it:
This is an automatically generated Delivery Status Notification.
Delivery to the following recipients failed.
Here is what gmail returned:
Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 553 553 mailbox…. is restricted (Mode: normal) (state 14).

It could be a number of things. Starting with the basics or ports and DNS? Is the exchange server publicly aval? MX records setup for the domain and pointed to your exchange server?
