Policy
Configure allowed extension types
Microsoft Edge
Policy overview
Key metadata and intent for this policy.
Supported OS tags: Windows7
Setting the policy controls which apps and extensions can be installed in Microsoft Edge, which hosts they can interact with, and limits runtime access. If you don't set this policy, there aren't any restrictions on acceptable extension and app types. Extensions and apps, which have a type that's not on the list can't be installed. Each value should be one of these strings: * "extension" * "theme" * "user_script" * "hosted_app" See the Microsoft Edge extensions documentation for more information about these types. Note: This policy also affects extensions and apps to be force-installed using 'ExtensionInstallForcelist' (Control which extensions are installed silently). Starting in Microsoft Edge version 149, the 'Microsoft365CopilotChatIconEnabled' (Control whether Microsoft 365 Copilot Chat shows in the Microsoft Edge for Business toolbar) policy controls the display of Copilot in the toolbar. Policy options mapping: * extension (extension) = Extension * theme (theme) = Theme * user_script (user_script) = User script * hosted_app (hosted_app) = Hosted app * legacy_packaged_app (legacy_packaged_app) = Legacy packaged app * platform_app (platform_app) = Platform app Use the preceding information when configuring this policy. Example value: hosted_app
