I work in a school district. We have Outlook 2003 or 2007. We all
have our own calendar events, birthdays, appointments and the like.
Every year our holidays and day off change. I would like to email the
new years school calendar so that everone can just click on the icon
and the dates will be merged into their calendar.

Create a school-wide holiday file. See if this helps:
