I need to create a rule that stops certain groups from sending email to the entire corporate office distribution group. However I need to be able to let them send email to individual members of said distribution group.
Is there a way to do so without having to allow each individual mailbox in the rule? I realize that would work but it would take a long time, also I realize that I could make another distribution group but I need to complete this ASAP. So for now I am looking for a workaround.
