[The use of Simple MAPI is discouraged. It may be altered or unavailable in subsequent versions of Windows.]

Simple MAPI is a set of functions and related data structures you can use to add messaging functionality to Windows-based applications written in C, C++, or Visual Basic.

For more information, see the following sections.

• Simple MAPI Functions
• Simple MAPI Structures

To use the Simple MAPI functions, compile your source code with Mapi.H, which contains definitions for all the functions, structures, constants, and data types. To call a Simple MAPI function, load Mapi32.dll and use theGetProcAddress function to acquire an entry point.

All strings passed to all MAPI calls and returned by all MAPI calls are null-terminated and must be specified in the current character set or code page of the caller's operating system process.
