Redirect incompatible sites from Internet Explorer to Microsoft Edge

Computer and userIntune-readyRedirectSitesFromInternetExplorerRedirectMode

Supported on Microsoft Edge version 87, Windows 7 or later

155.0.4283.62

What it does

This setting lets you specify whether Internet Explorer redirects navigations to sites that require a modern browser to Microsoft Edge. If you set this policy to 'Disable' ('Prevent redirection', value 0), Internet Explorer doesn't redirect any traffic to Microsoft Edge. If you set this policy to 'Sitelist', starting with Microsoft Edge major release 87, Internet Explorer (IE) redirects sites that require a modern browser to Microsoft Edge. (Note: The Sitelist setting is 'Redirect sites based on the incompatible sites sitelist', value 1.) When a site is redirected from Internet Explorer to Microsoft Edge, the Internet Explorer tab that started loading the site is closed if it had no prior content. Otherwise, the user is taken to a Microsoft help page that explains why the site was redirected to Microsoft Edge. When Microsoft Edge is launched to load an IE site, an information bar explains that the site works best in a modern browser. If you want to redirect all navigations, configure the Disable Internet Explorer 11 policy, which redirects all navigations from IE11 to Microsoft Edge. It also hides the IE11 app icon from the user after the first launch. If you don't configure this policy: - Starting with Microsoft Edge major release 87, you have the same experience as setting the policy to 'Sitelist': Internet Explorer redirects sites that require a modern browser to Microsoft Edge. - In the future, the default for your organization changes to automatically redirect all navigations. If you don't want automatic redirection, set this policy to 'Disable' or 'Sitelist'. For more information about this policy, see https://go.microsoft.com/fwlink/?linkid=2141715. Policy options mapping: * Disable (0) = Prevent redirection * Sitelist (1) = Redirect sites based on the incompatible sites sitelist Use the preceding information when configuring this policy.

The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
The generated payload is incomplete because one or more ADMX element values were not supplied: RedirectSitesFromInternetExplorerRedirectMode
