Outlook 2013 - Automatically accept meeting requests and remove canceled meetings

I enabled this option in Outlook 2013 :
"Automatically accept meeting requests and remove canceled meetings"

But, when I send an appointment, in the Inbox, I must confirm the appointment.


I have à Exchange 2007 server with Outlook 2013.

can you run a test email configuration to confirm the EWS is working?

Incoming meeting notifications will appear temporarily in your Mail Inbox and then Outlook will take over, auto-accept the meeting for you, send an acceptance notification back to the meeting organizer, and move the meeting notification from your Mail Inbox to your Sent Items folder. Meetings are only auto-accepted while Outlook is running.

Try to run the get-CalendarProcessing <mailbox_name> and check the automate processing

to make the mailbox autoaccept,
Set-CalendarProcessing <mailbox_name> -automateprocessing "AutoAccept"

to revert:
Set-CalendarProcessing <mailbox_name> -automateprocessing "AutoUpdate"

I have this result :

[PS] C:\>Set-MailboxCalendarSettings zorma1 -automateprocessing "AutoAccept"
Set-MailboxCalendarSettings : AutoAccept can only be enabled on resource mailboxes.
At line:1 char:28
+ Set-MailboxCalendarSettings  <<<< zorma1 -automateprocessing "AutoAccept"

Is it normal that you can not do it on a user mailbox?

damn .. this really hurts my brain .. let have a think overnight.

I know Exchange 2010 will work but Exchange 2007 is something interested.
Let me replicate this in my lab tomorrow to confirm whether will it take
I remember i use Outlook 2010 in exchange 2007 and it works like charm (via outlook method)
Jian An LimSolutions ArchitectCommented:
okay, i have tested this on production environment
it is Exchange 2007 sp3 with outlook 2013.
when Outlook is open, the calendar will process automatically (within seconds you will get a response), and when the outlook is off, it will not process until you next open Outlook.

so definitely something wrong with your outlook 2013.
have you had all the patches and hotfixes installed?
