Moving emails from Entourage to Outlook: How???

Hysterical female seeks help on moving her emails from Mac OS X Entourage to Win XP Outlook (2003).

Odd to be moving in this direction, I know, but it happens.

The problem is, from Entourage, I can only export the files as .mbox whereas in Outlook, I can only import from .pst and Eudora/Outlook Express.

Pleeease, does anyone know the solution to this?
