OWA is available in two different interfaces: Light and Premium. The Premium interface closely replicates the interface of Microsoft Office Outlook with additional features that are not available in the Light interface. The Light interface gives you faster access to the majority of the features you will use.
In order to access OWA Premium, you will require one of the listed combination of operating system and internet browser:
- Windows 8: Internet Explorer 10 or later, Firefox current version, Chrome current version
- Windows 7: Internet Explorer 9 or later, Firefox current version, Chrome current version
- Windows Vista: Internet Explorer 9, Firefox current version, Chrome current version
- Mac OS X v10.7 or later: Safari 6 or later, Firefox current version, Chrome current version
OWA Light works on most operating systems and most web browsers. See a comprehensive list of web browsers officially supported by Microsoft.
