Supported on Microsoft Edge version 84, Windows 7 or later

What it does

Configures the proxy settings for Microsoft Edge Application Guard. If you enable this policy, Microsoft Edge Application Guard ignores other sources of proxy configurations. If you don't configure this policy, Microsoft Edge Application Guard uses the proxy configuration of the host. This policy doesn't affect the proxy configuration of Microsoft Edge outside of Application Guard (on the host). The ProxyMode field lets you specify the proxy server used by Microsoft Edge Application Guard. The ProxyPacUrl field is a URL to a proxy.pac file. This policy doesn't affect the proxy configuration of Microsoft Edge outside of Application Guard (on the host). The ProxyMode field lets you specify the proxy server that's used by Microsoft Edge Application Guard. The ProxyPacUrl field is a URL for a proxy .pac file. The ProxyServer field is a URL for the proxy server. If you choose the 'direct' value as 'ProxyMode', all the other fields are ignored. If you choose the 'auto_detect' value as 'ProxyMode', all the other fields are ignored. If you choose the 'fixed_servers' value as 'ProxyMode', the 'ProxyServer' field is used. If you choose the 'pac_script' value as 'ProxyMode', the 'ProxyPacUrl' field is used. For more information about identifying Application Guard traffic via dual proxy, see https://go.microsoft.com/fwlink/?linkid=2134653. Example value: { "ProxyMode": "direct", "ProxyPacUrl": "https://internal.site/example.pac", "ProxyServer": "123.123.123.123:8080" } Compact example value: {"ProxyMode": "direct", "ProxyPacUrl": "https://internal.site/example.pac", "ProxyServer": "123.123.123.123:8080"}

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: ApplicationGuardContainerProxy
