#550 5.1.1 RESOLVER.ADR.RecipNotFound; not found ## Is not being sent to external emails

I have removed a user from AD and their email address from Exchange 2007.

When an internal email is sent to this deleted account, the recipient receives:

"#550 5.1.1 RESOLVER.ADR.RecipNotFound; not found ## " as they should.

But, if someone using an external email account sends to the deleted email address, they do not receive any bouce back at all.  I would like for everyone to receive a bounce back if the email address has been deleted from Exchange.

Is there a setting to turn this on or off?

Thank you for your help!

Please follow these steps to enable the NDR messages:
Open the Exchange Management Console
Expand the Organization Configuration folder
Click on Hub Transport
Select Remote Domains
Right-click the Default tab
Click on the Message Format
to turn on NDR's check "Allow non-delivery reports"

I hope this what you are looking for.
