Resource has declined your meeting because it is recurring

An administrator asked: When we add any new meeting request we get this error "Resource has declined your meeting because it is recurring. You must book each meeting separately with this resource."

Is the resource mailbox configured to decline recurring meetings? You can check this using Outlook or on the Exchange server using the Get-MailboxCalendarSettings cmdlet.

Get-MailboxCalendarSettings MeetingRoom_name |fl

Specifically, check the AutomateProcessing and AllowRecurringMeetings properties. AllowRecurringMeetings should be true if you want to allow users to book recurring meetings. Using AutoAccept means the resource will automatically accept or decline meetings.

AutomateProcessing : AutoAccept
AllowRecurringMeetings : True

Use the Set-MailboxCalendarSettings to change these properties.

If the property is set to True, you need to clean Outlook's free/busy cache using the /cleanfreebusy switch.

In the Run command, type outlook.exe /cleanfreebusy and press Enter.

Direct Booking in Outlook 2010

If you normally use direct booking, note that Outlook 2010 does not implement direct booking in the same manner as older versions. If the resource is configured for direct booking, the meeting will not be booked and , you won't receive an error message.

You can enable direct booking through group policy or by editing the registry on the problematic workstations.

HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Options\Calendar
DWORD: EnableDirectBooking
Value: 1

Group policy key:

HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\14.0\Outlook\Options\Calendar
DWORD: EnableDirectBooking
Value: 1

Configure in Outlook

You can also use Outlook to check the AllowRecurringMeetings setting. Open the resource mailbox using Outlook. Go to Tools, Options, Calendar Options, Resource Scheduling and verify that "Automatically decline recurring meeting requests" is not checked.

In Outlook 2010, look at File, Options, Calendar - Resource Scheduling is the last item on the page.
