TLS 1.0 and TLS 1.1 to be disabled by default in Microsoft Edge & IE11

As announced in October of 2018, Microsoft will soon disable Transport Layer Security (TLS) 1.0 and 1.1 by default in Microsoft browsers. In light of current global circumstances, we will be postponing this planned change—originally scheduled for the first half of 2020.

For the new Microsoft Edge (based on Chromium), TLS 1.0 and 1.1 are currently planned to be disabled by default no sooner than Microsoft Edge version 84 (currently planned for July 2020).

For all supported versions of Internet Explorer 11 and Microsoft Edge Legacy (EdgeHTML-based), TLS 1.0 and TLS 1.1 will be disabled by default as of September 8, 2020.

While these protocols will remain available for customers to re-enable as needed, we recommend that all organizations move off of TLS 1.0 and TLS 1.1 as soon as is practical. Newer versions of the TLS protocol enable more modern cryptography and are broadly supported across modern browsers, such as the new Microsoft Edge.
