Hey,

I've got with exchange 2013 allowing rooms to be double booked. It seems to allow it every room, even with new ones I create. The get-calendarprocessing settings are as follows:

[PS] C:\Windows\system32>Get-CalendarProcessing "testroom" | fl *


PSComputerName                      :COMPANY.ca
RunspaceId                          : 45ad788d-53bb-4bc3-b0b6-1a787e028be6

AllRequestInPolicy                  : False
AddAdditionalResponse               : False
AdditionalResponse                  :
RemoveOldMeetingMessages            : True
AddNewRequestsTentatively           : True
ProcessExternalMeetingMessages      : False
RemoveForwardedMeetingNotifications : False
MailboxOwnerId                      : COMPANY/Users/testroom
Identity                            : COMPANY/Users/testroom
IsValid                             : True
ObjectState                         : Changed

However, when I book a meeting in the room using the New meeting request in outlook, and then book another meeting during the same time, it allows it without complaint.

Is there a global setting or something I should check?

Regards,

Kevin

Hi,

Please try to use the below command:

Set-MailboxCalendarSettings -Identity "testroom" -AutomateProcessing AutoAccept -AllRequestOutOfPolicy $False 

If it doesn't work, We want to know the default setting of the new room.

Please create a new room and keep that it has default setting.

Then check if the issue persists.

For detailed information, please refer to the following link  :
