  • Site Mailboxes: Brings Exchange emails and SharePoint documents together. 
  • Outlook Web App: Offers three different UI layouts optimized for desktop, tablet, and mobile phone browsers. 
  • Ability to customize: Outlook and OWA by integrating apps from the Office marketplace.

The new "Napa" tools and/or HTML5 are Microsoft's preferred ways for developers to build these.

  • Combine Roles: A reduction in the number of available roles to two: a Client Access Server and a Mailbox Server role.
  • FAST Search: Now integrated into Exchange 2013 managed store to provide a more consistent (across Microsoft servers) indexing and searching experience.
