The rule is from a later version of the service. Some fields were not understood and have been ignored. This may cause the rule to be less restrictive than on the version where it was created. To mitigate any risk from this fallback behavior, ensure that the original rule is as specific as possible. To avoid this fallback behavior, create version-specific GPO's, or apply a Platform condition to the rule.
