Due to our organization policy, we want to disable "Originating IP" like (X-Received and X-Originating-IP) function in our Exchange 2013 for all internal & external senders, now I have noticed that when the employees are sending to each others within the organization, no "X-Originating-IP" is added to the message, but when they send from their Internet mobile devices, that field shows up.
Any idea how to disable that?
