Why is Internet Explorer 7 using the light version on OWA 2013?

Similar to OWA 2010, OWA 2013 comes in two versions

  • OWA Premium is what serves up the new desktop, tablet and phone optimized UI. You can get to this UI from desktops using Internet Explorer (IE) 8+, and newer versions of Safari, Chrome and Firefox. To get to the tablet and phone OWA UI, support is starting for Windows 8 tablets, and iOS6 on iPad2 and iPhone 4 or newer in the initial release. In the preview releases of OWA, you can use iOS5 since iOS6 isn’t released yet, but this will change since iOS6 includes several bug fixes necessary for the OWA experience to be great.
  • OWA Light, which largely remains the same as with the last release of OWA, is what you get on any browser not supported with OWA Premium or OWA Mini. It uses a very simple HTML4 based UI which works in pretty much any browser in existence. The most significant addition to the list of browsers which get OWA Light with OWA 2013 is IE7

The "premium" UI is the typical one that's used with newer browsers across PCs, tablets and smartphones. It's designed to work with Internet Explorer 8 and higher versions, as well as "newer versions of Safari, Chrome and Firefox,"

IE7 cannot handle any of the modes to the full capabilities of this UI, so it has been forced to use OWA lite.
