Microsoft also announced that Microsoft Edge Legacy support will be ending entirely on Maafter which time that browser will no longer receive security updates. Updated on August 26, 2020: Simultaneously with the original posting of this blog, Microsoft announced the end of support for Internet Explorer 11 with their Microsoft 365 web apps. We have served billions of requests to Internet Explorer 11 over the years, but it has gotten increasingly difficult to continue to support a 7-year-old browser that is locked in time in an otherwise constantly evolving environment where other browsers update almost on a monthly basis while continuing to innovate. Farewell, Edge Legacy, we hardly knew ye!) (Support is also ending for Microsoft Edge Legacy which has been superseded by the new Chromium-based Microsoft Edge that was released by Microsoft in January. This was originally announced for ArcGIS Online and ArcGIS Enterprise with the January 2020 update to the ArcGIS deprecation plans. Now the time has also come for Esri to begin phasing out support for Internet Explorer 11 in ArcGIS Online, ArcGIS Enterprise, and ArcGIS API for JavaScript. You have likely already seen many public websites and applications stating their end of support for Internet Explorer 11 over the past several years. It has not received feature updates since 2014 and has been superseded by Microsoft Edge released with Windows 10 and now also available for Windows 7, 8.1, and even macOS.

Internet Explorer 11 was released in 2013 and it is the last of the Internet Explorer line that harkens back to the original browser wars of the 1990s (remember Netscape!).
