What it does

This policy setting prevents the user from having enclosures (file attachments) downloaded from a feed to the user's computer. If you enable this policy setting, the user cannot set the Feed Sync Engine to download an enclosure through the Feed property page. A developer cannot change the download setting through the Feed APIs. If you disable or do not configure this policy setting, the user can set the Feed Sync Engine to download an enclosure through the Feed property page. A developer can change the download setting through the Feed APIs.

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.
