SYMPTOMS

Even if the MAPI_NO_COINIT flag is passed, MapiInitialize() may not handle different threading models correctly if Component Object Model (COM) has already been initialized.

CAUSE

This problem may occur if MapiInitialize() calls CoInitialize() regardless of whether or not the flag is passed, and then calls CoUninitialize if the flag was set, without first checking to see if CoInitialize initially failed. This behavior may cause CoUninitialize to be called too many times.
