Microsoft Imported ADMX Feature

Question

Is the latest Intune feature on Import ADMX work for Microsoft product(like Edge) ADMX or is this feature meant to work only for 3rd-part ADMX ?
Microsoft's article is not very clear on this: https://learn.microsoft.com/en-us/mem/intune/configuration/administrative-templates-import-custom

I tried testing it on a few policies, I am receiving errors:

The same setting when deployed from already existing Administrative Templates in Intune, it succeeds without any issue.

Answer 1

@IntuneUser , For this feature, both custom and third party ADMX and ADML templates can be imported.

From your description, it seems the Edge ADMX imported failed. Please check if we met all the following requirements.

If the above are all met but still get error, you need to open case to check this. Here is a link with the steps to open case for your reference:

Hope it can help.

Intune automatically imports and includes the Edge ADMX based policies so attempting to do this manually again will result in issues. WHy are you trying to import in what's already there?
