Outlook 2003, XPPro, Exchange 2003. ( All SPs )

Have 2 users - ostensibly identical configurations.
QuickBooks automatically e'Mails Invoices.

1 user get's no security warning the other does....
"A program is automatically trying to send e-mail messages on your behalf"

I can't see the difference in config, but I'd like to authorise QB to send
and get rid of the message.

Hints and pointers appreciated.
