SYMPTOMS
In Windows NT, if you attempt to start a program as a service that uses Windows NT Mail MAPI, the service fails to start the Mail spooler with MAPI error code 3 - MAPI_E_LOGIN_FAILURE.



CAUSE
MAPI for Windows NT does not support being started as a service.



WORKAROUND
Use one of these techniques to work around the problem:


 * Start the Mail client before starting the service.
 * Start the program from the command line instead of starting it as a service.



STATUS
Microsoft is researching this problem and will post new information in the Microsoft Knowledge Base as it becomes available.
