Exchange 2016 GenerateCopyOfDSNFor not working

Question
-
Hello
I have a problem with getting copies of NDR's to the postmaster mailbox. We just migrated from exchange 2010 to exchange 2016 and after we forwarded all the traffic to exchange 2016 the GenerateCopyOfDSNFor stopped working.
What i did to set it up:
Set-OrganizationConfig -MicrosoftExchangeRecipientReplyRecipient postmaster@domain.com
Set-TransportConfig -GenerateCopyOfDSNFor 5.1.1
Set-TransportConfig -ExternalPostmasterAddress postmaster@domain.com
The NDRs go out fine just the copy doest go to the postmaster mailbox
I also migrated the mailbox to exchange 2016 but still no effect.
Any ideas what i am doing wrong or is it just a bug or something?

Hi Casparj,
You can assign another existing mailbox (instead of postmaster ) to the Exchange recipient and check again:
Set-OrganizationConfig -MicrosoftExchangeRecipientReplyRecipient Administrator

Was this ever resolved? I have the same scenario, Exchange 2010 to 2016 migration and unable to get NDRs to Postmaster or any other mailbox for external senders. Thanks, RickiMonday, October 28, 2019 4:37 PM
