AutoAccept for Resources

Question

I have a conference room that no longer automatically accepts/declines meeting requests.  I have verified the calendar policies and that the AutoAccept flag is enabled.  The room mailbox accepts the messages to the Inbox but does not process
them.  I have about 30+ different rooms and equipment calendars and they are working fine.
We are a Exchange 2013 CU7 Hybrid environment.  All user mailboxes and resources are in Office 365.
PS C:\Windows\system32> Get-CalendarProcessing <ROOM> | fl *policy
RequestOutOfPolicy    : {}
AllRequestOutOfPolicy : False
BookInPolicy          : {}
AllBookInPolicy       : True
RequestInPolicy       : {}
AllRequestInPolicy    : False
PS C:\Windows\system32> Get-CalendarProcessing <ROOM> | fl automateprocessing
AutomateProcessing : AutoAccept
PS C:\Windows\system32> Get-MailboxFolderPermission <ROOM>:\calendar
FolderName           User                 AccessRights
Calendar             Default              {LimitedDetails}
Calendar             Anonymous            {Reviewer}
Calendar             <USER>         {Owner}

Hi,
According to your posting, the configuration for this room is correct. I suggest we can move this room mailbox to another database then check whether the issue persists.
Also run the following command to check the room mailbox:
get-mailbox <Identity>| fl *type*,*link*,*share*
