Hi everyone, I tried to create customized DSNs with the New-SystemMessage cmdlet. I have created both en\internal\5.2.3 and en\external\5.2.3 on my Hub Transport server. When I send an oversized message within the organization my customized DSN works flawlessly. But when someone sends a large message from outside the organization, all they get back is the standard English 5.2.3 DSN.Do I need to set anything else for external NDRs to work? Thanks, Marton

probably a -internal $true mix up. Check out the syntax here: http://technet.microsoft.com/en-us/library/aa998878.aspx

I'm not sure what you mean by mix up, but here's how I got it set up. Output of Get-SystemMessage | Format-List is as follows: Text : Blah blah blah, my custom textInternal : FalseLanguage : enDsnCode : 5.2.3QuotaMessageType :AdminDisplayName :ExchangeVersion : 0.1 (8.0.535.0)Name : 5.2.3DistinguishedName : CN=5.2.3,CN=External,CN=9,CN=DSN Customization,CN=Transport Settings,CN=MYORG,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=domain,DC=localIdentity : en\External\5.2.3Guid : ffd503b9-19a4-47cf-9a71-ea37198505a1ObjectCategory : domain.local/Configuration/Schema/ms-Exch-DSN-MessageObjectClass : {top, msExchDSNMessage}WhenChanged : 2007. 11. 13. 17:06:06WhenCreated : 2007. 11. 13. 16:16:56OriginatingServer : dc2.domain.localIsValid : True Text : Blah blah blah, my custom textInternal : TrueLanguage : enDsnCode : 5.2.3QuotaMessageType :AdminDisplayName :ExchangeVersion : 0.1 (8.0.535.0)Name : 5.2.3DistinguishedName : CN=5.2.3,CN=Internal,CN=9,CN=DSN Customization,CN=Transport Settings,CN=MYORG,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=domain,DC=localIdentity : en\Internal\5.2.3Guid : ba53e410-0e56-4ed4-987c-3a94df3c2905ObjectCategory : domain.local/Configuration/Schema/ms-Exch-DSN-MessageObjectClass : {top, msExchDSNMessage}WhenChanged : 2007. 11. 13. 16:24:22WhenCreated : 2007. 11. 13. 16:24:01OriginatingServer : dc2.domain.localIsValid : True This seems correct to me.

by mix-up i simply meant if you had entered the new-systemmessage cmdlet with -internal $true Looking at this output, it seems like it should work....sorry, unless i'm missing something i'm stumped.
