A MAPIINIT_0 is represented as a tuple of:
-  int : version
- This must be MAPI_INIT_VERSION.
-  int : flags
- MAPI initlization flags.
|MAPI_MULTITHREAD_NOTIFICATIONS||MAPI should generate notifications using a thread dedicated to notification handling rather than the first thread used to call mapi::MAPIInitialize.|
|MAPI_NT_SERVICE||The caller is running as a NT service. Callers that are not running in a Windows NT service should not set this flag; callers that are running as a service must set this flag.|
CommentsMultithreaded clients should set MAPI_MULTITHREAD_NOTIFICATIONS flag so that they can receive notifications on threads other than the first thread to call mapi::MAPIInitialize.
