want to sync outlook not windows media player

Hi my name is Douglas and im having problems with outlook. I just change my
computer ( the old one can sync correctly) and the new one (sony vaio fz240e)
have the same software (vista home premium and office 2003) that the old one
(vaio fe880e). When i try to sync the new one with my smartphone (sansung
i710 windows mobile 5.0) the sync occurs just with windows media player! I
tried to change settings in sync center but i notice that the computer can
establish conection with my phone, but there is no ways to make sync with
outlook, just with wmp. Do someone know how to make appropriate settings in
sync center to connect outlok instead Windows media playes?

thanks
