WF Definition Step: SendMail Problems

[Nobles, Diane]

Good afternoon fellow workflow'ers.  I am getting the following error when
using the Send Mail step in WFdefinition.  I am not using an organizational
unit, but rather Expression with WF initiator, later to add SAP users.  Can
anyone shed any light on this error and what is causing it??
