Message Store Object

The message store object is a MAPI object that provides a view of an information store. It contains messages and folders organized hierarchically and implements the IMsgStore interface, which is used to access the folders in an information store and the messages in those folders.

The Microsoft Exchange Server information stores are accessed through their message store objects:

• Public information store Contains public folders and resides on server computers.
• Private information store Contains users’ mailboxes on server computers.
• Offline information store Contains synchronized copies of folders stored on the server.
• Personal information store Stores documents and messages in .PST files on client computers.

For more information on accessing message store objects through MAPI, see Working with Information Stores.

You create a message store object to access a particular information store with a call to IMAPISession::OpenMsgStore. You destroy a message store object with a call to IUnknown::Release.

For more information on the IMsgStore interface, see Message Store Interface. For more information on information store properties declared by Microsoft Exchange Server and by MAPI, see Microsoft Exchange Server Information Store Properties and MAPI Message Store Properties.
