Office 365 users can reserve a meeting room even though it's already reserved for another meeting
Original KB number: 3066068
When an Office 365 user tries to schedule a meeting in a room that's already reserved for another meeting, the Calendar Attendant doesn't automatically decline the conflicting meeting request.
This issue occurs if the
AllRequestOutOfPolicy property of the room mailbox is set to True. This causes the room mailbox to ignore conflicting meeting requests.
To resolve this issue, set the
AllRequestOutOfPolicy property of the room mailbox to False. To do this, follow these steps:
Connect to Exchange Online by using remote PowerShell. For more information, see Connect to Exchange Online PowerShell.
Run the following command:
Get-CalendarProcessing -Identity "Meeting Room" | Set-CalendarProcessing -AllRequestOutOfPolicy $False
