Microsoft Edge
Define a list of allowed URLs
Supported on Microsoft Edge version 77, Windows 7 or later
What it does
Setting the policy provides access to the listed URLs as exceptions to 'URLBlocklist' (Block access to a list of URLs). Format the URL pattern according to https://go.microsoft.com/fwlink/?linkid=2095322. You can use this policy to open exceptions to restrictive blocklists. For example, you can include '*' in the blocklist to block all requests, and then use this policy to allow access to a limited list of URLs. You can use this policy to open exceptions to certain schemes, subdomains of other domains, ports, or specific paths. The most specific filter determines if a URL is blocked or allowed. The allowed list takes precedence over the blocked list. This policy is limited to 1000 entries; subsequent entries are ignored. This policy also allows the browser to automatically invoke external applications registered as protocol handlers for protocols like "tel:" or "ssh:". If you don't configure this policy, there are no exceptions to the blocklist in the 'URLBlocklist' policy. This policy doesn't work as expected with file://* wildcards. Example value: contoso.com https://ssl.server.com hosting.com/good_path https://server:8080/path .exact.hostname.com

- The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
- Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
- The generated payload is incomplete because one or more ADMX element values were not supplied: URLAllowlistDesc
