Cornerstone is retiring support for Microsoft Internet Explorer 11 and Microsoft Edge Legacy.

In order to keep up with browser security requirements and the latest software enhancements and to continue our focus on bringing you the most innovative technology, Cornerstone will not develop or test for Microsoft applications beyond their own support commitment. With the July '21 release, Cornerstone is withdrawing support and compatibility testing of IE11 and Edge Legacy.

On 17th August 2020, Microsoft announced that Microsoft Teams will stop supporting Internet Explorer 11 (IE11) on 30th November 2020 and Microsoft 365 products will end IE11 support on 17th August 2021. Read more in Microsoft’s announcement.

Cornerstone strongly recommends that you partner with your IT teams to review your browser usage and encourage your team to upgrade to supported browsers. Microsoft recommends the use of the new Microsoft Edge.
