URLBlocklist

Block access to a list of URLs

Supported versions

  • On Windows and macOS since 77 or later

Description

Define a list of sites, based on URL patterns, that are blocked (your users can't load them).

Format the URL pattern according to https://go.microsoft.com/fwlink/?linkid=2095322.

You can define exceptions in the URLAllowlist policy. These policies are limited to 1000 entries; subsequent entries are ignored.

Note that blocking internal 'edge://*' URLs isn't recommended - this may lead to unexpected errors.

This policy doesn't prevent the page from updating dynamically through JavaScript. For example, if you block 'contoso.com/abc', users might still be able to visit 'contoso.com' and click on a link to visit 'contoso.com/abc', as long as the page doesn't refresh.

If you don't configure this policy, no URLs are blocked.

This policy does not work as expected with file://* wildcards.
