Schema Changes Reference for Exchange 2007
Topic Last Modified: 2007-11-01
Microsoft Exchange Server 2007 adds many new attributes and classes to the Active Directory directory service schema and makes other modifications to existing classes and attributes. This topic provides information about the Active Directory schema changes that occur when you install Exchange 2007.
The Active Directory schema changes listed in this topic represent only those changes that are made by Exchange 2007. This topic does not include information about changes that are made when Microsoft Exchange Server 2003 is installed on a Microsoft Windows Server 2003 network.
Refer to the .ldf files for more information about changes to the Active Directory schema. The .ldf files are located in the \amd64\Setup\Data\ directory on the setup DVD.
Table 1 lists changed Active Directory schema classes that are not Exchange-specific.
