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.

Premium interface

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.

Light interface

Requirements for the Light interface

You receive the Light interface when you are not using one of the browsers or browser versions listed in the premium interface section above, or you have enabled the "Blind and low vision experience" option in OWA.
