Specifying the Status for In Progress Emails
The Email Activity Sent Status Code user property specifies the code that Siebel CRM uses in the EVENT_STATUS_LOV list of values that correspond to an outbound email that is in progress. The eMail Response client uses it to set the status of an outbound email that is in process or that is waiting for the Communications Outbound Manager or Email Manager to send this email. The value for this user property must contain a language-independent value that the EVENT_STATUS_LOV list of values contains. For example:
Queued
You must not deactivate this user property. You can modify the values for this user property. You cannot create a new instance of this user property.
