This policy setting allows you to specify whether or not the InfoPath client can access cross-domain data in untrusted forms.

If you enable this policy setting, users will not be able to retrieve cross-domain data unless the form is full trust or opened from a Trusted Location.

If you disable or do not configure this policy setting, users will be asked if they want to trust the data connections in a form when the form contains cross-domain data connections.
