To perform the following procedure, the account you use must be delegated the following:

• Exchange Organization Administrator role
  
  

To perform the following procedures on a computer that has the Edge Transport server role installed, you must log on by using an account that is a member of the local Administrators group on that computer.

For more information about permissions, delegating roles, and the rights that are required to administer Exchange Server 2007, see Permission Considerations.

Also, before you perform this procedure, you must specify the identity of the DSN message or messages that you want to view. For more information about how to specify the identity of a DSN message, see DSN Message Identity.

When you remove a customized DSN message, the DSN code that is associated with that message reverts to the original DSN message that is included with Exchange Server 2007. You can remove a customized DSN message by using the following command syntax:

	Copy Code
Remove-SystemMessage <Identity>

Note:
You cannot remove an original DSN message that is included with Exchange Server 2007. To change an original DSN message, you must create a new customized DSN message for the DSN code that you want to customize.

To use the Exchange Management Shell to remove an existing DSN message

For detailed syntax and parameter information, see Remove-SystemMessage.
