Details

By default, all extensions are allowed. However, if all extensions are blocked by setting the ‘ExtensionInstallBlockList’ policy to ‘*,’ users can only install extensions defined in this policy.

Solution

Set the policy value for ‘Computer Configuration/Administrative Templates/Microsoft Edge/Extensions/Allow specific extensions to be installed’ to ‘Enabled’. A list of allowlisted extensions may then be specified.
