High availability has become an essential part of the email services in many organizations around the world, which means that understanding how to deploy and maintain a highly available Exchange Server environment is a critical skill for Exchange Server administrators.

Although Microsoft Exchange Server is a single product it is made up of many different components, such as:

  • Client access – the protocols that allow mailbox access via Outlook, Outlook Web App (OWA), ActiveSync (mobile devices), and other clients.
  • Transport – SMTP communications and mail flow.
  • Mailbox – the databases hosting mailboxes.
  • Unified Messaging – the telephony integration services.
