Important: Open-Xchange has added support for the latest Microsoft Internet Explorer 8. At the same time, we will discontinue our support of the outdated Internet Explorer 6, though we will continue to fix bugs in the category "blockers" and "critical" for Internet Explorer 6 until April 30, 2010. Starting with the next major release, version 6.10, new features of Open-Xchange Server will only be optimized for Internet Explorer 7 and Internet Explorer 8 - as well as other browsers, like Firefox and Safari. As users of Internet Explorer 6 will not benefit from new features in Open-Xchange, we encourage you to update to the latest browser technology.
