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.

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*

Additionally, here is a helpful KB for your reference:

http://support.microsoft.com/en-us/kb/2005631

Regards,

Thank you for your response.  Here is the output from the command you provided.  I have reviewed the KB link you provided and this output matches the example in the KB. 

 Get-Mailbox -identity "ROOM" | fl *type*,*link*,*share*

ResourceType         : Room
RemoteRecipientType  : Migrated, RoomMailbox
RecipientType        : UserMailbox
RecipientTypeDetails : RoomMailbox
IsLinked             : False
LinkedMasterAccount  : NT AUTHORITY\SELF
IsShared             : False

I reran the command Set-CalendarProcessing  <ROOM>  -AutomateProcessing AutoAccept -ConflictPercentageAllowed 0 -maximumConflictInstances 0

Since this resource mailbox is in the cloud most of the KB is not relevant to this problem.
