I have a weird problem with our department shared calendar. If you
open up an appointment within it to see more details, the appointment
appears in your own calendar - even though it might be nothing to do
with you. I have no idea what might be causing it as it appears to
effect everyone, and there are no rules setup on the public folder. We
use outlook xp and exchange 2000. Anyone seen this before?

How are you creating the appointments in the public folder? There's nothing
built in that synchronizes data between a public folder and your mailbox
folders (although there is third party stuff that does this).
