I saw someone posted something similar but received no solution.

I have a calendar in the public folder used as the Conference Room
booking calendar. Different department heads were giving the Author
permission, I'm the folder Owner, the executive assistant is the Editor
because she needs the ability to cancel any meeting when CEO wants the
room. The problem is, whenever I or the exec. assistant view any of
the meetings in that calendar, it list one of our names as the Meeting
Organizer (depending on which one of us is viewing it). It's been
really frustrating because we don't know who actually scheduled the
meeting in the public calendar when we need to bump their meeting.

Ideas? I've been trying to fix this for over a year, getting really
really desperate.

Please help.
