Setting this policy controls extension management settings for Microsoft Edge, including those configured by other extension-related policies. This policy supersedes any legacy policies. This policy maps an extension ID or update URL to a specific configuration. You can define a default configuration using the special ID "*", which applies to extensions without a custom configuration. Note that any per-ID extension setting from either 'ExtensionInstallForcelist' (Control which extensions are installed silently), 'ExtensionInstallAllowlist' (Allow specific extensions to be installed), 'ExtensionInstallBlocklist' (Control which extensions cannot be installed), or 'ExtensionSettings' (Configure extension management settings) will only inherit 'installation_mode' and 'update_url' from the "*" defaults. It will not inherit any other properties. With an update URL, configuration applies to extensions with the exact update URL stated in the extension manifest. If the 'override_update_url' flag is set to true, the extension is installed and updated using the update URL specified in the 'ExtensionInstallForcelist' policy or in 'update_url' field in this policy. The flag 'override_update_url' is ignored if the 'update_url' is the Edge Add-ons website update URL. For more details, check out the detailed guide to ExtensionSettings policy available at https://go.microsoft.com/fwlink/?linkid=2161555. To block extensions from a particular third party store, you only need to block the update_url for that store. For example, if you want to block extensions from Chrome Web Store, you can use the following JSON. {"update_url:https://clients2.google.com/service/update2/crx":{"installation_mode":"blocked"}} Note that you can still use 'ExtensionInstallForcelist' and 'ExtensionInstallAllowlist' to allow / force install specific extensions even if the store is blocked using the JSON in the previous example. If the 'sidebar_auto_open_blocked' flag is set to true in an extension's configuration, the hub-app (sidebar app) corresponding to the specified extension will be prevented from automatically opening. On Windows instances, apps and extensions from outside the Microsoft Edge Add-ons website can only be forced installed if the instance is joined to a Microsoft Active Directory domain or joined to Microsoft Azure Active Directory®. On macOS instances, apps and extensions from outside the Microsoft Edge Add-ons website can only be force installed if the instance is managed via MDM, joined to a domain via MCX. 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.

Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
