If the Pushpage Manager created the distribution group from a converted subscription list that was tied to a pushpage job, they can change the distribution group type until that distribution group is tied to a pushpage job that is Scheduled, Running, Paused, Stopped or Sent.

In either of the above instances, if the Pushpage Manager wants a Public distribution group to be Private, they can copy the distribution group and set the Group Type of the copied distribution group to Private.
