How to Open a Website in Internet Explorer Mode With Microsoft Edge
Microsoft will no longer support the old Internet Explorer in June of 2021. However, they have, for now, made an option available to load a website in Internet Explorer mode.
When you enable this option, you can choose to reload a website in Internet Explorer mode when a website requires Internet Explorer for compatibility.
Click on the three dots in the top-right corner, or press Press Alt + F and click on Settings.
Click on Default browser.
Click Allow websites to be reloaded in Internet Explorer mode option.
Restart your browser when prompted.
You can now load a website in Internet Explorer by right-clicking on the tab and clicking on Refresh tab in Internet Explorer mode when available. Of course, Internet Explorer is so old now that you might have trouble finding a website that supports this feature.
