This works for an exchange server account, I did this on my PC @ work.
In Outlook Navigation Pane, right click on the folder you want to filter (calendar, tasks, contacts, etc...)
Select Properties from the menu
Click on Synchronization Tab
Click filter
Click more choices
Select the categories you want to allow to synch
OK
Click Tools -> Send/Receive
TaDaaa! Filtered by Categories.
It is a little counter intuitive, you select the categories that you want to synchronize not filter.
To allow synchronization of only items in the "Business" category, you select Business.
Here's a link to Microsoft Office Assistance, where I found the solution.
