Has anyone seen a situation where a room accepts an invitation when the room is already booked? Both employees got the acceptance emails. I checked via PowerShell and and setting for Allow Conflicts is false.

Yes, there are several "known exceptions" to the conflicts rule as detailed here: http://blogs.technet.com/b/exchange/archive/2012/01/23/recurring-meeting-requests-with-conflicting-i...

We actually do not want it to double book and I assumed from the settings that it would reject one of the requests but the room auto accepted both invites.

Ever find an answer for this issue?  This just started happening to here, and these were not recurring meetings.

We didn't find one that would work for us. We set our rooms to deny the series if the resource wasn't available for any of the meetings. It is harsh but it seems to have solved the double booking issue. We decided it was better than the confusion caused by the double booking.

We also are changing the responses from the rooms to say "Be sure you received the acceptance from the room, until you have that, the room is not booked."

I am wishing that the calendar invite would keep all the meetings if the room is available and only decline if the room is busy. Maybe someday.

Sorry I couldn't be of any help to you.
