Managing Exchange Server 2013 by using EAC

          Exchange Administration Center used for managing your Exchange Server 2013 deployment. It is graphical console that allows you to manage both an on-premises Exchange Server and an Exchange Online or hybrid Exchange deployment. This console is a replacement for the Exchange Management console (which exists in Exchange Server 2007 and 2010) and for the Exchange Control Panel (ECP).
          EAC is much faster and more responsive than the Exchange Management console and allows you to administer both Exchange on-premises and Exchange Online deployments from the same place. It allow you to permit or deny access to users trying to access the EAC from the Internet outside of your organizational environment, while still allowing access to an end-user’s Outlook Web App Options.
