Updated user interface and theme
As you can see, the user interface has changed only ever so slightly, keeping the original Outlook Web App feel to Outlook Live, the cloud email product part of the Live@edu educational suite. This version includes themes which allows greater customisability of the interface for the end user.
This version of Outlook Web App will be the version used in Office 365 for Education, which will be rolled out later this year.
