Outlook 2007 - viewing Chinese in To, From & Subject fields

I am now using Outlook 2007, I love it, however, I cannot view any Chinese in the From, To, Subject Fields, etc. I only see a bunch of question marks or gobally goop. I can view Chinese in the body of the email though. I have tried messing with the regional settings in XP, but everything is already installed for far east langauges.

Any one have other ideas?
