Não me lembro como funcionou no Outlook 2002, mas você não pode criar uma regra que exiba um "Alerta de área de trabalho" quando um novo email chegar?
Se isso não funcionar, talvez você esteja interessado no Add-in do Traylook para Outlook do Pergenex Software. Parece que ele traz notificações mais ou menos como as do Outlook 2007. Mas não é gratuito.
