I have an Exchange 2010 server, newly built. I want any NDRs received by a mailbox(we'll call it MB@mydomain) be forwarded to several external recipients. I know exchange is reluctant to forward NDR's, but does anyone know a way to force it to for good reasons?
At this point I have created an Inbox Rule to forward all incoming mail from this account to the external recipients (including my gmail address).
Any mail I send to this mailbox is forwarded using the server side rules I've created.
Unfortunately, when I send mail as this user to a nonexistent address, the NDRs are not forwarded. They just stay in the box.
