With a Shared calendar only show free/busy information

[Kamal]

So my company has set up exchange accounts/calenders for Conference Rooms, to
see the calendar which is shared among users. However, of course since it is
a shared calendar all users can just view the calendar and all events and
attendees. Is there a way to view the shared calendar but only to see the
free/busy information pretty much just see if the room is occupied during
that time. Remember this is for the calender, not the scheduling a meeting
aspect.

Let me know what options I have for this and please be as specific as
possible as I have been looking for a solution on this topic for days.

Thanks.
