I doubt we know the whole story, but even if you do find a way to make this work what stops her from... - emailing her work to her gmail/hotmail/yahoo account? - copying her email and putting it on a thumb drive? - printing it out and taking it home? If you are trying to stop her from taking "work material" home then you've got a much bigger problem.
