Hi, We have recently migrated from exchange 2007 to Exchange 2010 SP1. Now in Exchange 2010 I need to configure the Postmaster mailbox to receive a copy of all undelivered emails which are rejected by the Internal Exchange server to Internal users. I have already configured Postmaster to receive emails sent by Mailer-Daemon. Please suggest how I can configure the same. Thanks

Hi Amit, Kindly have a read on configuring postmaster email address on the below link.. http://technet.microsoft.com/en-us/library/bb430765.aspx After seting the postmaster email address - you have to create a mailbox and add the postmaster email address to the mailbox.

This is already configured. What I am looking for is: I want to configure postmaster to receive undelivered emails. E.g. if a user A on Exchange 2010 server sends an email and he gets an undelivered email from same server then a copy of this undelivered email should come to postmaster. This is basically to track who got undelivered email and why. Please suggest

Copying Internal NDRs to a Mailbox Perform the following procedure on a Hub Transport server in your organization to copy internal NDRs to a mailbox. To receive copies of internal NDRs, you must associate the mailbox that you created in the "Creating a Mailbox to Accept NDRs" section earlier in this topic to the Microsoft Exchange Recipient. If you don't associate a mailbox with the Microsoft Exchange Recipient, NDRs that are copied to the Microsoft Exchange Recipient are not captured. By default, no mailbox is associated with the Microsoft Exchange Recipient. To associate a mailbox with the Microsoft Exchange Recipient, specify the full name of the mailbox by using the following command: Set-OrganizationConfig -MicrosoftExchangeRecipientReplyRecipient <Recipient Identity> How to Copy NDRs to a Mailbox http://technet.microsoft.com/en-us/library/bb400930(EXCHG.80).aspxJames Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com
