Recently upgraded from Exchange 2003 to Exchange 2010.
All of my resource mailboxes are allowing conflicting meeting requests to be scheduled, even though in the window when you are scheduling it, it says "conflicts with another appointment".
Resource attendants are enabled, and the box for "allow conflicting meeting requests" is NOT checked.
Maximum conflict instances is 0, and conflict percentage allowed is 0.
And I am not scheduling any recurring meetings. If there is a meeting already schedule from 1-2 (for example) and I go on the calendar and schedule another meeting in the same resource from 12:30-2:00 it lets me schedule it, never declines it or anything.
I have looked around a bunch and can't seem to figure out what is wrong, so any assistance would be greatly appreciated.
