According to TechNet KB’s RemoteMailbox doesn’t exist in Exchange 2013 any longer. That has to wait until 2016.

Using get-mailbox? If so, you should be able to use get-remotemailbox.

I have a customer running Exchange 2010/2013 hybrid on prem and O365 cloud mailboxes. We need to set up an automated monitoring script for a cloud mailbox. 1. Can this be done from the 2013 hybrid server? 2. If 1. is true, how can this be done? Thanks. John Matteson
