Exchange Resource Mailbox not sending auto decline for double booking.

Set Exchange resource mailbox to send auto decline for double booking.

This is a topic that always seems to come up from the helpdesk team , in this post i will configure a resource mailbox to auto decline when there is a double booking.

In this post i will use the Exchange Powershell to configure the resource mailbox to auto send decline messages.

To control who can schedule a resource, use the following parameters with the Set-CalendarProcessing cmdlet:

To get the current “Calendar Processing” details of the Mailbox run the following commands.

Get-CalendarProcessing -Identity my.room5021 |fl

Let go ahead and set the CalendarProcessing to : AutoAccept

Set-CalendarProcessing -Identity "mcme.room5021" -AutomateProcessing AutoAccept

Now that we have set this , lets go ahead and look at some other examples as well.

This example allows all users to submit in-policy requests to the room mailbox Lazy Conference Room 01, but the request is still subject to approval by a delegate.

Set-CalendarProcessing -Identity "Lazy Conference Room 01" -AutomateProcessing AutoAccept -AllRequestInPolicy $true

This example allows the Calendar Attendant to accept out-of-policy requests from Alan Brewer to the room mailbox Room222. The request is still subject to approval by a delegate.

Set-CalendarProcessing -Identity "Room222" -AutomateProcessing AutoAccept -RequestOutOfPolicy AlanBrewer@contoso.com

This example allows a list of users to submit in-policy meeting requests to the equipment mailbox Car54.

Set-CalendarProcessing -Identity "Car54" -AutomateProcessing AutoAccept -BookInPolicy "ayla@contoso.com","tony@contoso.com"

This example rejects meeting requests from any user who isn’t a member of the Exchange organization.

Set-CalendarProcessing -Identity "Room222" -ProcessExternalMeetingMessages $false

For detailed syntax and parameter information, see Set-CalendarProcessing.
