Aimed largely at enterprises that still run apps and intranet sites written for Internet Explorer, the IE Mode is available in both the legacy Edge based on the EdgeHTML engine, as well as on Edge Chromium, whichstarted rolling out on Windows 10early last year before being expanded to other desktop and mobile platforms. However, since the legacy Edge itself has been deprecated, our tutorial will deal exclusively with Edge Chromium. So without further delay, let’s check out how you can enable or activate IE Mode in Microsoft Edge Chromium on your Windows 10 PC.

IE (Internet Explorer) Mode on Microsoft Edge Chromium is a compatibility mode that helps the browser render older sites and webpages written for Internet Explorer. It also enables enterprise users to use all of the sites their organization needs in a single browser.

The IE Mode uses the integrated Chromium engine for modern sites and the Trident MSHTML engine from Internet Explorer 11 (IE11) for legacy sites. As part of the functionality, only those sites that you specifically configure (via policy) will use IE mode, while all other sites will be rendered using the new engine.

You can easily enable IE Mode (Internet Explorer mode) on Microsoft Edge Chromium using in-app settings in a few simple steps. Here’s how you do it:

  2. Now selectDefault Browseron the left pane. If you’re not in full-screen mode, the option may be hidden behind a hamburger menu (three small parallel horizontal lines) on the top-left.

  3. Under the ‘Internet Explorer compatibility’ section in the right pane, turn on the toggle for ‘Allow sites to be reloaded in Internet Explorer mode’. Also, make sure the drop-down menu for ‘Let Internet Explorer open sites in Microsoft Edge’ retains the default option ofIncompatible sites only. Restart the browser for the change to take effect.
