Sending a copy of NDR’s to the Postmaster Mailbox

Troubleshooting Non-Delivery Reports (NDR) is a normal administrative task of anyone who supports emails.  The information provided on an NDR will help resolve the issue.  Getting the NDR’s would require the recipient to send a copy of the email to the administrator.  Which is also considered to be retroactive because you’re not proactively solving the issue(s).

Or, you can configure a mailbox to automatically receive a copy of those NDR’s.  This method allows the administrator to troubleshoot and proactively resolve issues before receiving any tickets.

1. To make sure the company has not already setup a postmaster account open powershell and type:
• Get-TransportServer
  
  The ExternalPostmasterAddress has not been configured because it’s empty.
2. To assign a mailbox type the following command:
• Set-TransportServer -ExternalPostmasterAddress postmaster@domain.com
  Excute the command below to make the change on all the Hub Transport
• Get-TransportServer | Set-TransportServer -ExternalPostmasterAddress postmaster@domain.com:
3. Now you must associate an internal mailbox to receive the NDR’s.
• Set-OrganizationConfig -MicrosoftExchangeRecipientReplyRecipient postmaster@domain.com

Make sure to create a postmaster mailbox for the email delivery.  This is done the same way a users mailbox is created.
