Starting with Microsoft Edge Stable version 87 set to be released this next month, Microsoft will redirect users to Microsoft Edge from Internet Explorer when they try to access websites that are incompatible with the latter. 

It is said that the users will be shown a one-time dialog box that will explain why they're getting redirected. Thereafter, their data will then be imported to Edge. 

A new feature called startup boost, Microsoft is also testing a new feature to improve the startup time of the Edge browser.

Enabling Edge availability more quickly once launched, the feature will launch a set of Microsoft Edge processes in the background.

As an optional setting in Microsoft Edge 88, when launching from the taskbar, desktop, and hyperlinks embedded in other applications, the new feature will also enable Microsoft Edge to start more quickly.  

While the remaining Microsoft 365 apps and services will no longer support the browser starting August 17, 2021,the Microsoft Teams Web app will stop supporting Internet Explorer by the end of next month.
