Outlook Web App (OWA) provides two distinctly different interfaces, Premium or Light, depending on the version number of the browser you use to access it.

The Premium interface comes closest to replicating the actual Microsoft Office Outlook experience, with some right-click functionality and access to the full feature set.
Requirements for the Premium interface
You receive the Premium interface when you are using Internet Explorer 7 and above, Firefox 3 and above, Safari 3 on a Mac, and Google Chrome 5 and above.
