Use Outlook express on two users in XP

Hi,I’ve recently upgraded from win 98se to win XP. I need to have to desktops (user profiles) one for myself and one for my wife. in win 98se we could share the same,favs,inbox and all local folders whilst using Outlook Express. But in win XP it seems that when one user downloads the mail the other can’t see it and it’s the same from the other user. we are both logged on as administators. What we want is to both have the same outlook express programs so we see each others mail and local mail folders….please help i don’t have much hair left….Mark
