Resource Delegation Not Working

Question

On Exchange 2010 SP3 RU8v2, for the life of me I can't figure out why resource delegation is not functioning as expected.  The issue is that the approval email is not being sent to the delegate but instead it's sitting in the resource's inbox.
I verified with a bunch of articles and it should be quite straight forward to set this up:
1. Create room resource
2. "Specify users who are allowed to submit in-policy meeting requests that will be automatically approved" - Check, Selected recipients, (blank)
3. "Specify who can submit in-policy meeting requests that are subject to approval by a resource mailbox delegate"  - Check, All users
4. "Enable the Resource Booking Attendant..." - Uncheck
5. Add user to "Specify delegates of this mailbox"
6. "Forward meeting requests to delegates" - Check
7. Set-CalendarProcessing -Identity test-room2 -AutomateProcessing:None
Under this configuration, all users adding the resource into the meeting request will trigger an approval email to the delegate but it's simply not working.  Why?

Hi,
The "Enable the Resource Booking Attendant..." should be checked in the resource mailbox delegate configuration. We also can run the following command in EMS:
Set-CalendarProcessing -Identity test-room2 -AutomateProcessing AutoAccept
Then check whether the issue persists.
