This article shows by example how you can use OLE Messaging as an
alternative to using a MAPI Session and MAPI Messages .ocx controls to send
mail. This functionality relies on MAPI OLE Automation support at the
operating system level but doesn't require that an .ocx file be added to a
form. The MAPI .ocx files currently available use Simple MAPI as opposed to
MAPI 1.0, so they are superseded by this.

The OLE Messaging Library is installed with the MAPI Software Development
Kit (SDK). When the OLE Messaging Library is available, the following flag
is set in the Win.ini file:
[Mail]
OLEMessaging=1
And it can be found in the registry. Under Windows 95 and Windows NT 4.0
you will find it in:
HKEY_Local_Machine\SOFTWARE\Microsoft\Windows Messaging Subsystem.
