How to enable Internet Explorer mode on Microsoft Edge

Microsoft’s updated Edge browser includes Internet Explorer mode — or IE mode — a feature that renders older IE websites as Internet Explorer 11 pages.

The latest generation of the Edge browser uses the Chromium platform, an open source browser project that aims to make the web faster, safer and more stable for users. With Internet Explorer mode included in Edge, end users can work with modern and legacy apps without having to switch between browsers or rely on the retired Internet Explorer browser.

Administrators can easily enable the feature on their managed desktops so that certain web pages are automatically rendered in IE mode when users access them. Alternatively, users can manually enable the feature to apply IE mode to other websites.

What is Internet Explorer mode, and why is it important?

Internet Explorer mode allows users to access modern and ancient websites in a single browser. The Chromium engine built into the browser uses the technology underlying Google Chrome, making it ideal for modern web applications. However, the Chromium engine is not intended for IE-based websites, which some organizations continue to support. As a result, Edge includes the Trident (MSHTML) engine from Internet Explorer 11, which allows users to work with modern web applications created for IE.

When users enter IE mode, in-page navigation such as links, forms, and scripts all remain on the page, so users can browse the Web as if they were working in Internet Explorer 11. However, actions such as clicking the back button or entering a different URL in the address bar will cause the browser to slip back into Chromium mode unless the target page is also enabled for IE mode.

Edge Chromium compatibility mode supports most Internet Explorer features, such as Edge extensions, document modes, enterprise modes, security zone policies, browser helpers, and Internet Explorer F12 developer tools. However, IE mode does not support features such as Internet Explorer toolbars, navigation menu policies, or the Edge F12 developer tools.

When exiting Internet Explorer, organizations can use Internet Explorer mode to continue viewing IE-based websites, which will be permanently disabled on February 14, 2023.

While implementing Internet Explorer mode is easy, IT efforts must focus on maintaining the site’s inventory. However, as IE-based applications reach end-of-life and more applications use modern technologies, the list can grow smaller over time.
