Dear all Does Ex07 and Ex10 have the ability to forward NDR reports at a mailbox level. To elaborate I have two mailboxes, however I only monitor mailbox 1 for mail occasionally, and I have setup a mail forward rule within the Ex07 EMC on the mailbox level so that mailbox 1 forwards all mail to mailbox 2. I sent some mails form mailbox 1 and never monitored this mailbox for sometime, however when I did check it I noticed a number of NDRs, which never got forwards to mailbox 2. I assume this maybe by design to prevent any mail loop, however I would like to learn more about how exchange handles NRDs in this fashion.

Yes, its by design to prevent NDR storms or mail loop. The following technet article should help you. However, its only to copy all NDR messages to one mailbox. http://technet.microsoft.com/en-us/library/bb400930.aspx
