SYMPTOMS
Consider the following scenario. In Microsoft CRM 1.2, you have multiple recipients in the From field or in the Sender field in one of the following activities:
 * Phone Call
 * Fax
 * Letter

Then, you upgrade to Microsoft Dynamics CRM 3.0. When you try to open one of the activities in Microsoft Dynamics CRM 3.0, the activity does not open. Additionally, you receive an error message that resembles the following error message:

Exception Details: System.ArgumentException: This lookup can only display one item. Lookup ID = from



CAUSE
This problem may occur because Microsoft Dynamics CRM 3.0 allows only one recipient in the From field or in the Sender field of an activity. This problem occurs because of a design change in Microsoft Dynamics CRM 3.0.
