What is Outlook Anywhere?

 Outlook Anywhere, formerly known as RPC over HTTP is a feature that allows users to use MS Outlook outside the business organization without VPN (Virtual Private Network).

  • For Exchange Server 2003, 2007 and 2010 versions manually configure RCP over HTTP.
  • For Exchange Server 2013 and 2016, the Outlook Anywhere enabled by default.
