A MAPIINIT_0 is represented as a tuple of:
Value | Meaning |
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. |
