Supported on: Microsoft Edge version 97, Windows 7 or later
Path in the GPO console
Computer Configuration\Administrative Templates\Microsoft Edge User Configuration\Administrative Templates\Microsoft Edge Description
This policy lets sites configured to open in Internet Explorer mode to be opened by Microsoft Edge for testing on a modern browser without removing them from the site list. Users can configure this setting in the "More tools" menu by selecting 'Open sites in Microsoft Edge'. If you enable this policy, the option to 'Open sites in Microsoft Edge' is visible under "More tools". Users use this option to test IE mode sites on a modern browser. If you disable or don't configure this policy, users can't see the option 'Open in Microsoft Edge' under the "More tools" menu. However, users can access this menu option with the --ie-mode-test flag.
Registry
Software\Policies\Microsoft\Edge Software\Policies\Microsoft\Edge Value name: InternetExplorerModeTabInEdgeModeAllowed
Enabled: InternetExplorerModeTabInEdgeModeAllowed = 1
Disabled: InternetExplorerModeTabInEdgeModeAllowed = 0
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.
