RESOLUTION

MORE INFORMATION

Messaging Application Programming Interface (MAPI) is a set of functions that mail-enabled and mail-aware programs can use to create, transfer, store, and otherwise handle mail messages. It contains tools that program developers can use to define the purpose and content of mail messages, and provides flexibility in the management of stored mail messages. MAPI also provides a common interface that program developers can use to create mail-enabled and mail-aware programs, independent of the underlying messaging system. Messaging clients provide an interface for interaction with the Windows Messaging System (WMS). This interaction typically includes a request for services from MAPI-compliant providers, such as message stores and address books.

Microsoft recommends that vendors upgrade their programs to use Collaboration Data Objects (CDO).
