What it does
This policy setting allows you to determine whether users can open, view, edit, or save PowerPoint files with the format specified by the title of this policy setting. If you enable this policy setting, you can specify whether users can open, view, edit, or save files. The options that can be selected are below. Note: Not all options may be available for this policy setting. - Do not block: The file type will not be blocked. - Save blocked: Saving of the file type will be blocked. - Open/Save blocked, use open policy: Both opening and saving of the file type will be blocked. The file will open based on the policy setting configured in the "default file block behavior" key. - Block: Both opening and saving of the file type will be blocked, and the file will not open. - Open in Protected View: Both opening and saving of the file type will be blocked, and the option to edit the file type will not be enabled. - Allow editing and open in Protected View: Both opening and saving of the file type will be blocked, and the option to edit will be enabled. If you disable or do not configure this policy setting, the file type will not be blocked.

- 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.
