mobile sync center

hi all

i run a o2 xda exec smartphone and have just upgraded to windows vista home
premium.

when i was running windos xp and active sync 4.5 i could sync all my
contacts, calenders and so on to outlook (2002) that came as part of the
phone package and it all worked fine.

i have installed the uopdate for the new mobile active sync center in vista
and have upgraded my outlook to the one that comes with office 2007 , but
when i sync it says that it has done it ok but i can seem to find my
contacts and other info any where on the pc.

any ideas if it installes a file somewhere else.....?

i keep all my details upto date on the pc and then sync it to my mobile so i
have details when im on the move, but it just aint having any of it.

any ideas.
