One of our clients just went through an upgrade from Exch 2003 -> 2007. Following the upgrade, when someone attempted to book a meeting using a conference room resource, it would no longer immediately reject the conflict with a popup message in Outlook. Instead, the people invited to the meeting all got meeting invitations and the conference room automatically "replied" saying "declined". Users feel like they're looking quite ridiculous when having to send out multiple meeting requests to everyone as a result.
I did some research and found the following Exch 2007 shell command that should have fixed this problem, but it's not working. Any ideas?
