pop up appointments
 

I like to use pop up appointments as reminders of things that I need to get
done. Our office just changed to outlook 2007, and now every reminder popup
that I set comes up on every computer in the office. How can I set pop up
reminders that just come up on my computer without unwanted reminders to
everyone else. We are using microsoft exchange. I tried setting up my own
calendar and checking only my own, as well as unchecking my calendar on all
the other calendars in the office, but the pop ups still go to all computers.
What can I do to fix this?
