DSN Message Identity

Microsoft Exchange Server 2007 will reach end of support on April 11, 2017. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.


Applies to: Exchange Server 2007, Exchange Server 2007 SP1, Exchange Server 2007 SP2, Exchange Server 2007 SP3

This topic explains the syntax for the identity of a customized DSN message. The identity is the customized DSN message's GUID or a string that consists of the following values:

  • Locale   This variable specifies the locale of the language that the DSN message is displayed in. For a list of locale codes that you can use with the New-SystemMessage command, see Supported Locales for Use with System Messages.

  • Internal or External   This variable specifies whether the DSN message is sent only to senders who are part of the internal Exchange Server 2007 organization or also to senders outside the Exchange Server 2007 organization. You can use the Internal option when you want to include a specific e-mail contact or resolution in DSN messages that are sent to internal senders, but do not want to expose that information to senders outside your organization.

  • DSN code   This variable specifies the DSN code of the customized DSN message.

The syntax of the DSN message identity is <Locale>\<Internal or External>\<DSN code>.

For each DSN code, you can create more than one customized DSN message, which can target internal senders or external senders, and different locales. The following list shows some of the possible configurations for the DSN code 5.1.2:

  • Display DSN messages to Internal senders with an English (en) locale

  • Display DSN messages to External senders with an English (en) locale

  • Display DSN messages to Internal senders with a Japanese (ja) locale

  • Display DSN messages to External senders with a Japanese (ja) locale
