[This is pre-release documentation and subject to change in future releases.]
You can use Outlook Web Access together with any browser that supports HTML 3.2 and ECMA. This includes Internet Explorer, Mozilla Firefox, or Apple Safari, and other Web browsers on computers that run UNIX, Apple Macintosh, or Microsoft Windows.
Outlook Web Access Premium
To use the complete set of features available in Outlook Web Access Premium with Microsoft Exchange, you must use Internet Explorer 7 or a later version.
Outlook Web Access Light
The Outlook Web Access Light client is optimized for accessibility, including blind and low vision users. The Light client provides fewer features, and is sometimes faster. You may want to use the Light client if you are on a slow connection or using a computer with unusually strict browser security settings. If you are using a browser other than Internet Explorer 7 or later, you can only use the Light client.
For information about how to use the Light client with Internet Explorer 7 or later, see "Accessibility" in General Tab [ http://technet.microsoft.com/en-us/exchangelabshelp/ms.exch.ecp.owaoptionsgeneral(printer).aspx ] .
