This article was previously published under Q180172 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.
