If you disable the "Track e-mail sent between CRM users as two activities" feature in Microsoft Dynamics CRM 4.0, e-mail messages from a CRM user to a queue are not delivered. Additionally, if a workflow rule sends an e-mail message to a queue, e-mail messages that are sent by the workflow rule are not delivered. This problem affects both tracked messages and untracked messages.
