We have a hybrid environment with Exchange 2010.
On premise environment contains several conference room resource mailboxes; those are configured to auto accept meeting requests. On-premise users are able to book meetings with the room mailboxes and the bookings are accepted automatically.
Office 365 users cannot - the meeting request is not accepted.
Is it supported?

However creating a transport rule did not solve the issue for us so far.
Any advice will be appreciated.
