Specifying the Manager That Sends Email

The Email Manager Compatibility Mode user property specifies how to send email messages. It must specify one of the following values:

• Y. The business component uses Mail Manager to send email messages.
• N. The Outbound Communications Manager sends email messages.

You can configure Siebel CRM to deactivate this user property or modify the value for it, but not to create a new instance of it.
