If you have access to a Microsoft Exchange server you usually use Microsoft Outlook on your desktop PC.  There is an extension to Microsoft Exchange server to give access on the internet through a web interface (webmail).  OWA Webmail uses this web interface to access your mail on your iOS device, so you do not have to concern yourself with IT security issues and protocols.  It can connect to an Outlook Web App (OWA) server. What is an OWA server?  NOTE: It is not a general webmail client, so you cannot use it for Gmail, Hotmail, Yahoo mail etc.  If you are on the go you usually are not able to use Microsoft Outlook.  This interface is called Outlook Web App.  The app does not sync anything with your device, all messages, contacts etc. remain on your server.  OWA Webmail is an iOS mail client app.  This connection is through an internal net.  IMPORTANT NOTE for OFFICE 365 users: The app uses the light version of OWA, so "Outlook Settings", "Options", "General", "Outlook Web App version", "Use the light version of Outlook Web App" checkbox must be checked. - Outlook Web App 2010 (tested with version 14. 3. 224.
