How to Copy all NDRs/DSN to a mailbox in Exchange 2013

Exchange Server 2013 uses delivery status notifications (DSN) to provide non-delivery reports (NDRs) and other status messages to message senders

All NDRs Generated from the server can be forwarded to a mailbox so that you can watch over internal NDR’s and External NDR’s to be proactive from getting blacklisted.

Also it helps to be proactive to get in touch with internal users when they struggle with NDR’s

Note : It can be forwarded only to a Mailbox – Not to a Distribution Group – It cannot be forwarded to a Distribution Group from Postmaster mailbox as well.

Step 1 :

First Login to ECP – Create a Mailbox with your primary address – Postmaster@testcareexchange.biz

Make your Display Name only PostMaster

Note – Make sure you have a good amount of mailbox size. otherwise once its full . It will stop receiving NDR emails

Step 2 :

By Default External PostMaster Address will be Empty

To Catch all External NDR’s (Common Scenario – When a mail is sent to a User from external world which doesn’t exist in our Server)

Set-TransportConfig -ExternalPostmasterAddress postmaster@testcareexchange.biz

Step 3 :

To Catch All internal NDR’s (Common Scenario – When a mail is sent to a Internal User to a internal User which doesn’t exist in our Server)

Set-OrganizationConfig -MicrosoftExchangeRecipientReplyRecipient Postmaster@testcareexchange.biz

Step 4 :

To Set What all the NDR’s you want to catch from the server. –

-5.1.1 – am specifically adding as we are doing a GAL sync in my scenario and deleting/recreating users often so i want to catch all NDR’s which says (User Doesn’t exist)

Run (These are list of Common NDR’s)

Set-TransportConfig -GenerateCopyOfDSNFor 5.4.8,5.4.6,5.4.4,5.2.4,5.2.0,5.1.4,5.1.1

To See Common Enhanced Codes (DSN Codes)

For Example

To Remove or ADD DSN Codes later

Set-TransportConfig -GenerateCopyOfDSNFor @{Add=”5.7.5″; Remove=”5.7.1″}

Only to Add

Set-TransportConfig -GenerateCopyOfDSNFor @{Add=”5.7.1″}

Step 5:

Now I added the postmaster account in my outlook . It started collecting my NDR’s
