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

  • This partition includes information,AD Sites ( Exchange uses to route the mail) Site base routing topology

  • Address and display templates
  • Administrative groups
  • Client access settings
  • Connections

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.
