Exchange 2010 and Active Directory Data




Where does exchange keeps its information in active directory? This is one of the frequent question I am asked and I decide to give little information

Exchange keeps , stores its own information with in the .DIT database.

.DIT database and its partitions

Domain Partition ( resident directory object)

  • Stores information default containers
  • Organizational units
  • The containers hold domain specific data
  • Users,Computers etc
  • Exchange updated the objects in this partition to support the exchange functionality
  • Recipient information

Configuration partition

  • Forest-wide information
  • This partition includes information,AD Sites ( Exchange uses to route the mail) Site base routing topology
  • Exchange Global settings
  • Transport settings
  • mailbox policies
  • UM dial plans
  • Address lists
  • Address and display templates
  • Administrative groups
  • Client access settings
  • Connections
  • Messaging records management, UM policies
  • Global settings
  • E-mail address policies

Schema Partition

  • Stores classes and attributes
  • Exchange prep work and installation changes the schema
  • Schema classes define all the types of objects which can be created and stored in AD
  • Exchange installation adds many classes and attributes to AD schema, these classes be used for exchange specific object agents connectors etc.
