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. Default setting: Disabled or not configured Related policies: -Configure the Enterprise Mode Site List -Send all intranet sites to Internet Explorer 11

Export Builder
BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
