The legacy Edge browser will soon be officially replaced with the new version for everyone through an upcoming Windows update. Previously, Microsoft offered users the option of manually downloading the new version of Edge themselves at any time, but they did warn that the legacy version would be replaced in the future. On 03/09/2021, the legacy Edge browser will reach its end of life and will no longer receive security updates. Microsoft has also announced the end of support for Internet Explorer 11 (IE 11) on apps such as Teams and Microsoft 365. Starting on 9/30/2020, Microsoft Teams will no longer support IE 11. On 08/17/2021, Microsoft 365 will also no longer support IE 11. Microsoft has said that “This mean that the after above dates, customers will have a degraded experience or will be unable to connect to Microsoft 365 apps and services on IE 11. For degraded experiences, new Microsoft 365 features will not be available or certain features may cease to work when accessing the app or service via IE 11”.
