I'm looking for a solution to sync to two calendars:

Calendar 1 is for work entries on the company's exchange server. This should contain all calendar entries in the "Buisness" group or however I can mark it.

Calendar 2 is for personal entries on a local Outlook pst or elsewhere. This should contain the entries for the "Personal" group.

I basically want to keep my personal entries away from company servers where they can be read by sysadmins etc, but at the same time want to be able to sync exchange-based entries for work. I am not using wireless sync, just the regular hotsync.
Doyou have suggestions how to do this?
