contacts

i am having a problem with a users contacts..he is using office xp. we changed servers and his win 2k created him another user..this did the samething on several workstations, but they all work correctly. his though if you click the contacts icon on the left bar it brings up his contacts and he can add new ones there, but when you go to send new email and choose the personal contacts from there it does not disply the correct contacts. i right clicked the icon on the left and told it to put these contacts in the list of available ones and it still does not show the correct ones…what is going on here? as i said he is using office xp and windows 2000 professional os…any ideas?
thanks sr
