Have an unusual problem. Our environment - Exchange 2007/Outlook 2007. Our conference rooms are set up as Room Mailboxes, and most meeting requests are auto-accepted properly. Occasionally we get this problem: Sender adds a conference room to a meeting request by selecting "Rooms". Conference room shows up on the attendee list as a Room resource. When the meeting request is sent, the sender does not get an acceptance or decline notification. When you look at the room calendar, the meeting shows on the calendar as tentative, and when you open the meeting request from the room calendar and look at the list of attendees, the room does not show up at all! We've not been able to pin this down to a specific user or room mailbox - it seems to be totally random across all users and room mailboxes. Any ideas?

Hi Have you setup the mailbox so it uses automateprocessing? http://technet.microsoft.com/en-us/library/aa996340(EXCHG.80).aspx Use either cmdlet or owa to setup it up.. set-mailbox -id mailboxid -AutomateProcessing AutoAcceptJonas Andersson MCTS: Microsoft Exchange Server 2010, Configuration | MCITP: EMA | MCSE/MCSA Blog: http://www.testlabs.se/blog
