I am using Nigel Coates 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 all have.
