Exchange Server 2013 Preview – Services Overview

With the introduction of Exchange Server 2013 Preview, Microsoft has made some changes to the Windows Services that are required to run Exchange. Please remember this is a Preview (BETA) version of Exchange Server and anything written here could change once the product goes RTM (Released To Manufacturer). A couple of noticible changes are the removal of the System Attendant and Address Book services. There are nine new services including additional ones for POP3 and IMAP support.

* Please note this is a comparison between a multi-role Exchange 2010 server (CAS, Mailbox and Hub) and an Exchange 2013 server with the CAS and Mailbox roles installed.

Missing in Exchange Server 2013 Preview
