Navision Application Server and Outlook email send

I don’t pretend to know much about NAS and email, pardon my ignorance in this issue I’m having:

I have a Navision table which holds the email messages ready to be sent. i created a report to loop thru these email entries and use CU Mail.NewMessage to send them out one by one. When a user manually runs the report, everything get sent.

When the report is called (as a Job Queue Entry) thru NAS, the mail is not send.

We’ve tried to create a email account for NAS logon with the same setup as the user email account profile but to no avail. Could anyone help? Many thanks.
