as office coordinator I have permissions that allow me to access our 3
meeting room calendars to make corrections/delete meetings scheduled by
others. I sometimes book meetings in those meeting rooms through my calendar
for myself and for others. The problem that crops up is the failure of the
meeting room calendar to decline a meeting that conflicts with one I've
scheduled previously. This only happens to meetings that I've booked,
through my own calendar. If anyone else has booked a meeting that conflicts
with a later request Outlook will decline the later meeting.

Any ideas how to fix this? IT here hasn't figured out how but thinks it has
something to with the permissions I have to access the meeting room calendars
and Outlook treating it like my personal/default calendar, which does allow
conflicts be booked.

Thanks.
