PRB: "Login has failed" Error Using the MAPISession Control

• Microsoft Visual Basic Learning, Professional, and Enterprise Editions for Windows, version 6.0
• Microsoft Visual Basic Standard and Enterprise Editions for Windows, versions 4.0, 5.0

SYMPTOMS

When calling the SignOn method of the MAPISession control, the following error may occur:

Run-Time Error '32003' Login has failed.

CAUSE

The LogonUI property of the MAPISession control is set to False and the UserName property of the control contains an invalid profile name or is empty.

RESOLUTION

Set the UserName Property of the MAPISession control equal to a profile name that exists on the machine before the SignOn method of the control is called.

STATUS

This behavior is by design.

MORE INFORMATION

The MAPI 1.0 specification requires a profile to log on to a messaging session. The MAPISession control was written before the MAPI 1.0 specification was established. In order to use this control to establish a MAPI 1.0 session and prevent the Choose Profile dialog box from being displayed, the Username property must be used to pass the name of the profile needed to sign on.
