Extended Support for Accessing Lightning Experience Using Microsoft Internet Explorer Version 11

We previously communicated that the end of support date for Internet Explorer version 11 (IE11) for Lightning Experience was December 16, 2017. We received your feedback, and as a result are offering Extended Support for IE11. This extended support is available through December 31, 2020.
Lightning Experience is available in: Group, Professional, Enterprise, Performance, Unlimited, and Developer Editions

We believe that this extended period will give you the time you need to migrate from IE11 to more modern and secure browsers, while still allowing you to take advantage of the benefits of Lightning Experience now.
