On my previews post, I promise you that will see step by step the process of
Exchange Server 2013 Preview installation in Windows Server 2012. 

The new Exchange Server 2013, split in 2 roles Client Access Server and Mailbox Server (In addition, Exchange 2013 Preview works with the Exchange 2010 Edge server role.)
The Mailbox server
includes all the traditional server components found in Exchange 2010:
the
Client Access protocols, Hub Transport service, Mailbox databases, and Unified Messaging. The Mailbox server handles all activity for a given mailbox.
The
Client Access server provides authentication, redirection, and proxy services. The Client Access server itself doesn't do any data rendering. The Client

Access server is a thin and stateless server. There is never anything queued or stored on the Client Access server. The Client Access server offers all the
usual client access protocols: HTTP, POP and IMAP, and SMTP.

Before we proceed, we need to check the prerequisites for Exchange Server 2013, let’s see what we need to check before we begin:

  •  Make sure that the functional level of your forest is at least Windows Server 2003, and that the schema master is
    running Windows Server 2003 with SP1 or later.
  • The full installation option of Windows Server 2012 and Windows Server 2008 R2 SP1 must be used for all servers
    running Exchange 2013 Preview server roles or management tools.
  • You must first join the computer to the appropriate internal Active Directory forest and domain.
  • Some prerequisites require you to reboot the server to complete installation.
