SYMPTOMS
When Outlook Express is the default mail client, the MAPILogon function ignores the profile name and password parameters.



CAUSE
Because Outlook Express does not use profiles, MAPILogon uses the default identity.



STATUS
This behavior is by design.



MORE INFORMATION
The Outlook Express implementation of Simple MAPI checks if the process is running interactively, obtains a session, and then optionally performs a send and receive operation.

MAPILogon fails with a MAPI_E_FAILURE error if the MAPI_LOGON_UI flag is passed and the process is not running interactively (in other words, if the process is a service).

MAPILogon performs a send and receive operation if the MAPI_FORCE_DOWNLOAD flag is passed.
