There's nothing out of the box in Exchange 2007 that will achieve this for you. Some options are: GAL Sync with IIFP/MIIS/ILM/FIM (http://www.msexchange.org/tutorials/GAL-Sync-Identity-Integration-Feature-Pack-IIFP.html) SimpleSync (http://www.dirwiz.com/simplesync/) There are better federation options in Exchange 2010.
