Microsoft will release Office 2016 soon, this new Office have interesting new features:

  • The new apps offer full retina display.
  • The look and feel is the same like Ofice 2013 for Windows, or almost the same
  • Outlook 2016 supports now 100% Office 365, and only works with Exchange 2010 or above

System Requirements

To configure Outlook 2016 with EWS for Zimbra Collaboration need the next:
