Exchange 2010 with a test conference room as a resource mailbox.
The setup is working fine except one major trouble. The requestor receives an email notifying them the room is tentative awaiting approval, so far so good. Meanwhile the invitees have all received the invite and are now accepting the invitation, yet we are not sure the room will be approved.
How does one stop this action and have the invitees emails wait until the delegate approves the room use?
