Our users can see the details of everyone's calendars if
they go to schedule a meeting request. We want this to only show the
free/busy times, not the actual subject and details of the
appointments. We're using Outlook 2003. I've looked all over and
haven't been able to find a solution to this. Currently, if I go to
my Outlook Calendar, File-> New Meeting Request, click on the
Scheduling tab, and start adding people to the list... I'm able to
view all the details of these people's appointments. What needs to be
done so that I am only able to view the blue bar showing they are busy
with something, but I don't want to be able to see the subject or any
details of their appointment.

We tried to go to Tools, Options, Calendar Options, Planner Options, and unchecked all settings in that box. However, this did not seem to help. Do we need to do some kind of refresh? Is there more to it than this? Is there possible a setting on the Exchange server that needs to be changed?
I also tried changing 'Anonymous' permission's to 'none'. Other people have said this help them, but it did not help us. We do not have the option of 'free/busy' under permissions.
