Policy
Check OLE objects
This policy setting determines whether Office checks that an OLE object is properly categorized before loading it. If you enable this policy setting, you can select one of the following options: - Do not check: Office loads OLE objects without checking if they are properly categorized. - Override IE kill bit list: Office uses the category list to override IE kill bit checks. (This is also the default behavior for this policy setting). - Strict allow list: Office only loads properly categorized OLE objects. If you disable or do not configure this policy setting, Office uses the category list to override IE kill bit checks.
