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.
