Prep Schema Overview

Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.

The Prep Schema step extends the schema in Active Directory to include classes and attributes specific to Office Communications Server 2007. This is the first procedure run to prepare your environment for your Office Communications Server 2007 deployment. This procedure is required and run only once in the Active Directory forest. See the Active Directory Preparation section later in this guide for specific steps and credentials required to run this procedure.

Office Communications Server 2007 adds new classes and attributes and objects to the Active Directory schema. These classes and attributes are described in detail in the Active Directory Schema Reference section later in this guide.
