Why cant i scan multiple documents to multiple outlook emails?

This is an outlook 2000 problem. We have a Brother multi function fax “8460n” with 3 users on it, one of them can “scan to email” multiple sheets of paper and send each one of them to a seperate open email to be sent out. My other users scan multiple papers but they all go into one email. Is there a setting in outlook to change how this happens? I have called brother twice and they tell me its an outlook problem. This is my first post so i thank you in advance!!
