Custom DSN message nor custom rejection message is appearing when Transport Rule Blocks incoming e-mail.

Question

Good Afternoon,
      My Customer is running Exchange 2013 CU5 that has a transport rule that is supposed to reject any email from a particular user as that user is no longer with the company. The transport rule rejects the message, BUT, it does
not show the Custom DSN. It shows the default message:
Delivery has failed to these recipients or groups:
[email protected] Your message wasn't delivered because the recipient's email provider rejected it.
Diagnostic information for administrators:
Generating server: EXMBX01.DOMAIN.LOCAL
[email protected] Remote Server returned '< #5.7.169 smtp;550 5.7.169 TRANSPORT.RULES.RejectMessage; the message was rejected by organization policy>'
I have looked up the transport rule in Exchange:
Get-TransportRule "User Reject" | fl *Reject*,Description
RejectMessageEnhancedStatusCode   : 5.7.169
RejectMessageReasonText           : This E-MAIL Address is no longer in service. Please Contact
                                    [email protected] for assistance
SmtpRejectMessageRejectText       :
SmtpRejectMessageRejectStatusCode :
Description                                  : If the message:
Is sent to '[email protected]'
and Is received from 'Outside the organization'
Take the following actions:
Set audit severity level to 'High'
and reject the message and include the explanation 'This E-MAIL
Address is no longer in service. Please Contact
[email protected] for assistance' with the status code: '5.7.169'
I tried setting up to separate external DSN messages and tried both with the same results:
Get-SystemMessage | ft -a -wr
Identity            Text
en\External\5.7.69  This E-MAIL Address is no longer in service. Please Contact [email protected] for assistance.
en\External\5.7.169 This E-MAIL Address is no longer in service. Please Contact [email protected] for assistance.
I tried to change the SmtpRejectMessageRejectText on both Exchange servers and got the following error:
Set-TransportRule -Identity "User Reject" -SMTPRejectMessageRejectText "This E-MAIL Addre
ss is no longer in service. Please Contact [email protected] for assistance"
A specified parameter isn't valid on a server with the Hub Transport role installed.
    + CategoryInfo          : InvalidArgument: (SmtpRejectMessageRejectText:String) [Set-TransportRule], ArgumentExcep

I really am having issues finding and answer. Any assistance would be greatful!

Hi Lance,
Thanks for your update.
According to the error that you pasted, "A specified parameter isn't valid on a server with the Hub Transport role installed.", it seems you have no proper permission to use some specific parameters.
Even if there are many parameters in the Technet article
http://technet.microsoft.com/en-us/library/bb125138(v=exchg.150).aspx , you may not have access to some parameters if they're not included in the permissions assigned to you. You need Organization Management and Records Management permissions, see
the following links:
