Show message when opening sites in Internet Explorer

You can configure Microsoft Edge to open a site automatically in Internet Explorer 11 and choose to display a notification before the site opens. If you want to display a notification, you must enable Configure the Enterprise Mode Site List or Send all intranets sites to Internet Explorer 11 or both.

If enabled, the notification appears on a new page. If you want users to continue in Microsoft Edge, select the Show Keep going in Microsoft Edge option from the drop-down list under Options.

If disabled or not configured, the default app behavior occurs and no additional page displays.
