Microsoft Exchange is the standard Windows interface for email, voice mail, FAX, and other communication media. Applications interact with Microsoft Exchange by using the Messaging API (MAPI) and support services and components.
Note
For more information about MAPI, see the documentation included in the Win32 SDK.
Microsoft Exchange allows you to create support for an information service. An information service is a utility that enables messaging applications to send and receive messages and files, store items in an information store, obtain user addressing information, or any combination of these functions.
