Internet Explorer: Stop support from August 2021

Microsoft towards the end of IE 11 and EDGE Legacy
There is a very precise roadmap, which will include a series of steps. On November 30 this year, Microsoft Teams will no longer support Internet Explorer 11, but Microsoft 365 (M365) apps will continue to do so. Subsequently, in March 2021, support for Microsoft EDGE Legacy will permanently cease. Finally, on August 17, 2021, the M365 suite (and all other Microsoft services) will permanently stop supporting Internet Explorer 11.Just a few days ago, one of the browsers Web that made the history of the Internet celebrated its 25th birthday. According to the roadmap, there will be a twenty-sixth one just before the final demise and - to be completely honest - we will easily get over it.
