Active Directory objects are required for the deployment and operation of Microsoft Exchange Server 2007 Unified Messaging (UM). The Active Directory UM objects connect the telephony infrastructure and the Exchange Server 2007 Unified Messaging Active Directory environment.

UM Active Directory Objects

The UM Active Directory objects enable the integration of Exchange Server 2007 Unified Messaging into the Active Directory directory service and the existing telephony infrastructure. Active Directory acts as a container for all the UM objects that are created and their configuration settings. Each UM object within Exchange Server 2007 is necessary to support Unified Messaging in an Active Directory environment. Some UM Active Directory objects are created to logically represent a telephony hardware device whereas others are created to represent a telephony dial plan for an organization or to support a specific feature of Exchange Server 2007 Unified Messaging. The following figure illustrates the relationships between the Unified Messaging objects that are found in Active Directory.

UM Logical Relationships

There exists a tightly integrated and interconnected relationship between the UM Active Directory objects and the features that are available in Exchange Server 2007 Unified Messaging. In order to successfully plan and deploy Exchange Server 2007 Unified Messaging in your organization you must fully understand this logical relationship between each of the UM objects.
