We are updating the timeframe for disabling TLS 1.0 and TLS 1.1 by default for Internet Explorer and EdgeHTML, the rendering engine for the WebView control. TLS 1.0 and TLS 1.1 will be disabled by default for both starting September 13, 2022.

Organizations that wish to disable TLS 1.0 and TLS 1.1 before that date may might do so using Group Policy. The Microsoft Edge Legacy desktop application is no longer in scope for this timeframe, as it reached end of support on March 9, 2021.

Please note: We are not deprecating TLS 1.0 and TLS 1.1 support. We are simply disabling it by default, giving organizations the option to turn it back on through Group Policy (if needed, for compatibility reasons). Individuals can turn it back on for their personal devices by navigating to Tools > Internet Options > Advanced in Internet Explorer.

For Microsoft Edge (based on Chromium), TLS 1.0 and TLS 1.1 were disabled by default starting in Microsoft Edge, version 84. The SSLVersionMin policy that permitted the enablment of legacy protocol versions was removed starting in Microsoft Edge, version 91.
