finding missing email address

[techQ7A]

We hage an email address (abuse@abc.com) in our domain that we need to
have all inbound mail sent to the mailbox mailtest. The problem is we
can't find the user account that this email address belongs to. I've
tried AD queries, searching manually, searching exchange and can't find
out where this email address is in AD/Exchange. It already exists, but
i don't know where.. We simply need to configure all email sent to
abuse@abc.com to go to the mailtest mailbox. Is there an easy way to
do this? I feel i'm going the wrong direction on this one.. Any
suggestions?
