This policy setting lets you configure whether to use Enterprise Mode and the Enterprise Mode Site List to address common compatibility problems with legacy apps. If you enable this setting, Microsoft Edge looks for the Enterprise Mode Site List XML file. This file includes the sites and domains that need to be viewed using Internet Explorer 11 and Enterprise Mode. If you disable or don't configure this setting, Microsoft Edge won't use the Enterprise Mode Site List XML file. In this case, employees might experience compatibility problems while using legacy apps.

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.
