Frequently our HR department sends out emails to the employees and of course we have employees who have a questions but clicks 'Reply All' then we have a free for all. I've gone into exchange-->properties on the distribution group (universal)-->exchange general-->message restrictions and selected 'Only from:' me. Which works partially:
1. When user tries to send an email to the group (Clicks 'New E-mail') then they are denied.
2. If the users hits reply or reply all then delivery takes place.
How do I keep users from replying or replying-all to these E-mails?
