Title: GAL Sync with the Identity Integration Feature Pack (IIFP) Author: Marc Grote Summary: The Windows 2003 Forest is the logical boundary of Exchange 2003. Microsoft recommends deploying only one Active Directory Forest whenever possible. There are many reasons for single forest deployment beginning with the administrative overhead through the need to synchronize the Global Address Lists of Exchange 2003 between two forests to provide a central GAL. But what if you have more than one forest with Exchange 2003 (through a merger or acquisition)? In this article I will explain in high level steps how to synchronize the GALs (Global Access Lists) of two Exchange 2003 organizations with the help of IIFP. This article should give you an overview about this complex process. Link: http://www.MSExchange.org/tutorials/GAL-Sync-Identity-Integration-Feature-Pack-IIFP.html
