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:
Exception Details: System.ArgumentException: This lookup can only display one item. Lookup ID = from
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.
This problem was corrected in Microsoft Dynamics CRM 3.0 Update Rollup 3.
