Hi rares_dumitrescu,
use Active Directory Users and Computers console, open "Find", then in the "Users, computers and groups" dialog, choose the Exchange tab, select "Show only Exchange recipients" and "users with Exchange mailbox". That should do the trick for you.

Hope it helps, Elbereth

Beware: the "Exchange" tab in ADUC is only available if you connect to the Exchange server, or if you have installed the Exchange administration tools on your machine.

The easiest way is to use an LDAP query. This is a very basic search, but should be sufficient for what you requested.

(&(objectCategory=user)(mailNickname=*)(homeMDB=*))

open ad users and computers
select find on on your domain
in the find box, expand your options and select custom search
next to the custom search box you have advanced
enter your ldap query there

good luck!
