Prevent users from removing Application Guard protection on files.

This policy setting allows you to control whether users can remove Application Guard protection and open a document with full trust in Office.

If you enable this policy setting, users can continue to work with Office documents in Application Guard, however, they cannot remove protection and open a document outside Application Guard.

If you disable or do not configure this policy settings, Office will by default allow users to remove protection and open a document with full trust.

Note: This policy setting only applies to Microsoft 365 Apps for enterprise.

Supported on: At least Windows 10 Server, Windows 10 or Windows 10 RT
