SUMMARY
=======
MAPI32.DLL, the dynamic-link library for 32-bit Messaging Application Program
Interface (MAPI) calls, is a component of Windows NT Mail that functions as a
client for a Microsoft Mail for PC Networks postoffice. However, MAPI32.DLL does
not support multi-threaded calls.
MORE INFORMATION
================
Developers may use MAPI32.DLL, much like the 16-bit MAPI.DLL found in Microsoft
Mail for Windows, by making 32-bit calls from the application they are
designing. Developers may call from the 32-bit application directly, or from
16-bit calls that subsequently get converted (thunked) to 32-bit calls via the
MAPI.DLL thunking layer that is also provided with Windows NT Mail. However,
when making calls directly to MAPI32.DLL a single thread must be used from the
calling application. MAPI32.DLL does not support applications that make
multi-threaded calls, although multiple processes are supported.
