Turn off blocking of outdated ActiveX controls for Internet Explorer on specific domains

Computer and userNative Intune settingVerMgmtDomainAllowlist

Supported on At least Internet Explorer 8.0

22H2 · 1.0

What it does

This policy setting allows you to manage a list of domains on which Internet Explorer will stop blocking outdated ActiveX controls. Outdated ActiveX controls are never blocked in the Intranet Zone. If you enable this policy setting, you can enter a custom list of domains for which outdated ActiveX controls won't be blocked in Internet Explorer. Each domain entry must be formatted like one of the following: 1. "domain.name.TLD". For example, if you want to include *.contoso.com/*, use "contoso.com" 2. "hostname". For example, if you want to include http://example, use "example" 3. "file:///path/filename.htm". For example, use "file:///C:/Users/contoso/Desktop/index.htm" If you disable or don't configure this policy setting, the list is deleted and Internet Explorer continues to block specific outdated ActiveX controls on all domains in the Internet Zone. For more information, see "Outdated ActiveX Controls" in the Internet Explorer TechNet library.

These deployment candidates come from the ADMX template; they are separate from the native CSP mapping above.

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: DomainList
