End of Support for Internet Explorer 8 and Windows XP/Outlook

As of January 9th, 2017, LuxSci is ending support for Internet Explorer 8 and Outlook (all versions) running on Windows XP.

Internet Explorer 8.  This very old browser has worked to varying degrees with LuxSci.  Starting mid-January, LuxSci will be explicitly dropping support for Internet Explorer 8 by using new JavaScript libraries that do not support Internet Explorer 8.  Microsoft ended all support for Internet Explorer 8 on all versions of Windows on January 12th, 2016.  It ended all support for it on Windows XP (where it was primarily used) in April, 2014.

Internet Explorer 8 is very old, unsupported, and insecure.  It does not support many of the modern web standards used by modern web sites.  Anyone who is still using Internet Explorer 8 should either upgrade to a newer version of Internet Explorer (or Edge) and switch to an alternate supported browser such as Chrome or FireFox.

Windows XP and Outlook. In the interest of security, LuxSci often has to change the list of encryption ciphers supported by its servers — dropping those that are deemed too insecure and adding new ones.  Starting January 9th, LuxSci will be pushing out changes that remove support for the last TLS cipher that we supported that was also supported by Outlook running on Windows XP.  Once this change happens, Outlook on Windows XP will no longer be able to make secure IMAP, POP, or SMTP connections to LuxSci servers.    This will apply to any version of Outlook running on XP, as Outlook uses the (old) encryption services built into XP itself.  Windows XP itself has not been supported since April, 2014, and should be avoided for security reasons at this point.

Anyone affected by this change should either (a) upgrade to a newer version of Windows, (b) use an alternate email program that brings its own encryption libraries (e.g. Mozilla Thunderbird), or (c) use LuxSci WebMail directly using a supported web browser.

Outlook running on newer operating systems will continue to be supported as usual.
