The Exchange store is a storage platform that provides a single repository for managing multiple types of information in one infrastructure.

Note:
Microsoft Exchange Server 2007 tracks the attributes of its components across multiple servers by storing the attributes centrally in the Active Directory directory service, which contains objects for a number of Exchange 2007 components, including administrative groups, storage groups, and databases.
Note:
To assure the highest possible levels of availability for your Exchange organization, you can employ specialized and sophisticated storage group and database management methods. For more information about managing for high availability, see High Availability Strategies.

The following topics in this section provide an overview of the Exchange 2007 store components:
