I am using Outlook 2003 with Exchange.

I have set up a public calendar and then I used folder assistant on the
administration tab in properties to automatically email the appointment to a
user. On that user's pc, I set up a rule/filter to automatically add the
incoming appointment to their personal calendar.

Now my question. I want to do this same thing with my personal calendar. I
want to automatically email the appointment that I create on my personal
calendar to several exchange users. But, the folder assistant section on the
administratration tab in properties is greyed out. What am I missing?

Is the folder assistant only available on public folders? I am trying to
figure out a way to share calendars with as few clicks as possible.
