Finding an aliased email address in Active Directory

>From blogger Gim McBee on: http://mostlyexchange.blogspot.co.uk/2006/03/solving-e-mail-address-alre ady-exists.html Using the Windows 2003 Active Directory Users and Computers utility, right click on the domain, choose Find. In the Find: dropdown list, choose “Custom Search” and in the In: dropdown list, choose “Entire Directory”. Click the Advanced property page and enter the following LDAP query (in my example, at least): proxyaddresses=smtp:snuffy@domain.com Click Find and you should find the object that already has that SMTP address. Thanks Rich!
