Moving to the present day, Internet Explorer is only used to run proprietary applications that only work with its code. Precisely for this reason Microsoft has provided a IE mode on Edge, to completely replace your outdated browser that has now fallen into oblivion.
Microsoft urged users to gradually stop using Internet Explorer 11, until its official retirement scheduled for 15 June of the 2022. To "incentivize" the migration to more advanced web browsing programs, the company has placed some limitations on accessing Microsoft Teams from the web browser and from 17 August Internet Explorer will no longer be compatible with various Microsoft services, such as OneDrive and Outlook.
In this year, companies that use the web browser will have to migrate to the "Internet Explorer" mode in Edge, to adapt as soon as possible and allow the good old web browser to be permanently retired. It is estimated that, currently, still the 4,5% of users use Internet Explorer, preferring it to much more modern web browsing programs such as Edge, based on the same system as Chrome.
Goodbye Internet Explorer, Microsoft will retire the web browser in 2022
