Exchange 2007, NDRs on Replies to Hidden Users from Outside the Org
Posted on 2009-07-13
In Exchange 2007, if a message is sent from a hidden mailbox to an external user and that user replies, should that message normally generate an NDR? We are experiencing this behaviour and are interested in changing it. In other words, we want it to be possible to reply to a hidden mailbox from outside the organization. First question, should this be working by default. Second question, how do we make it do it?
