Microsoft is extending some of the targeted “end of support” deadlines due to impact of the pandemic.  TLS 1.0 first emerged around 1999 & two decades later these protocols are rated as non-secure & unsafe verses more current network protocols.  While originally targeted for phase out in 1st half of 2020, an extension for the latter part of 2020 was just announced — giving all parties a little more time to convert.

Microsoft announced on Tuesday that its plans to drop support for Transport Layer Security (TLS) protocols 1.0 and 1.1 in its browsers will get delayed by a few months until the second half of this year.  All browser makers are dropping such support, or have already dropped such support, for those security protocols, favoring the use of TLS 1.2 or higher instead. Microsoft had previously indicated, back in October 2018, that TLS 1.0 and 1.1 support would be removed from its Microsoft Edge and Internet Explorer 11 browsers “in the first half of 2020.”
