Resource mailbox :Subject not removed and organizer not visible in subject after setting permissions

Question

Hi,
I'm configuring some meeting room mailboxes, and would like to hide the subject and content, and add the meeting organizer into the subject field.
I've configured the next permissions :
Set-MailboxFolderPermission -Identity "[email protected]:\calendar" -User default -AccessRights LimitedDetails
Set-CalendarProcessing -Identity "[email protected]" -AddOrganizerToSubject $true -DeleteComments $false -DeleteSubject $true
Unfortunately the subject is still visible, and the organizer doesn't get filled in into the subject field.
Exchange 2013 SP1 / Outlook 2010 SP1 
These are the settings :
Get-MailboxFolderPermission "[email protected]:\calendar"
FolderName           User                 AccessRights
Calendar             Default              {LimitedDetails}
Calendar             Anonymous            {None}
Calendar             User One
         {Editor}
Get-Calendarprocessing

MailboxOwnerId                      : ..
Identity                            : ..
IsValid                             : True
PS : I've already changed autoupdate to autoaccept to test, but the result is the same.
I want the delegate to approve the meeting when someone makes a booking

Hi,
DeleteSubject parameter, AddOrganizerToSubject parameter and DeleteComments parameter are ignored unless the AutomateProcessing parameter is set to AutoAccept. From the above description, the AutomateProcessing is AutoUpdate. I recommend you use the following
cmdlet to achieve your goal.
Set-CalendarProcessing -Identity xxx -AutomateProcessing AutoAccept -DeleteSubject $true -AddOrganizerToSubject $false -DeleteComments $false
Hope it helps.
