Hi @TomDuany-5896 ,

Do you mean that extensions configured via this policy not showed in Application Guard window? If this is the case, have you enabled the extensions policy on your Application Guard configuration? Just refer to this doc, and as mentioned, it should be supported starting from Microsoft Edge version 81.

Hello,
When we open Microsoft Defender Application Guard window we see extension is getting an empty object when trying to read from chrome.storage.managed:

When running in normal mode, the same command is working as expected: the values that are in
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge\3rdparty are returned.
