Room mailbox auto accept in a hybrid environment


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?

I've seen this post:

However creating a transport rule did not solve the issue for us so far.

Any advice will be appreciated.




Hi Leonid,

Glad to hear that. Thanks for sharing. Mailboxes in hybrid need to have this smtp address *** Email address is removed for privacy ***.
