Active Directory Schema Changes
Microsoft Exchange Server 2007 will reach end of support on April 11, 2017. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.
Applies to: Exchange Server 2007
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 Microsoft Exchange.
The Active Directory schema changes listed in this document 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.
Changes to Existing Class-Schema and Attribute-Schema Classes
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.

New Object IDs
The following tables contain the new object identifiers that are used by Exchange 2007 in an Active Directory forest. Many objects are grouped into ranges. For instance, 1.2.840.113556.1.4.7000.102.50477 - 1.2.840.113556.1.4.7000.102.50481 represents five objects. A range of objects does not necessarily mean they are related by function.
