I am using your MapiMail, and it works flawlessly with Outlook. However, in the main office they are using "Expressit:. MapiMail gives an error if Expressit is NOT running, but works properly if it IS running.

The error is:

Error #: 1429
Message: OLE IDispatch exception code 0 from MAPISession: Unspecified Failure has occurred..
Program: PROCEDURE CUSMAPI.CREATESESSION
Code: THIS.oSession.SignOn()


Is there something that I the programmer can do to prevent this error? Is there a way to check to see if they are running their MAPI client (and then warn them to run it). Or can I force the MAPI client to start?

Thanks for any advice you have.
