SUMMARY

Before you can start a Simple MAPI session with a MAPI program, you may have to make sure that Simple MAPI is available on your computer.

MORE INFORMATION

To see if Simple MAPI is available on your computer, open the WIN.INI file, and look for the MAPI entry under the Mail section. The MAPI entry will have a value of 1 if Simple MAPI is installed and 0 if it is not installed.

For example, the MAPI entry will look similar to the following if Simple MAPI is installed:

[Mail]
MAPI=1


With the release of MAPI version 1.0, it is a good idea to also check the MAPIX entry for the availability of Extended MAPI, CMC entry for Common Mail Calls, and OLEMessaging for OLE Messaging.

For example, the following entries are for Extended MAPI:

[Mail]
MAPI=1
MAPIX=1
CMC=1
OLEMessaging=1

Note: Microsoft Windows 95 and Microsoft Windows NT use the WIN.INI file for backward compatibility.
