SPD Workflow cannot send email to group(s) from initiation form


Customer develops SharePoint Designer workflow, set Initiation Form to collect parameter of type Person or Group. Workflow steps include "Send an Email" action with "To" as look up to the Person or Group parameter collected from Initiation Form.

Run the workflow, after execute all steps, workflow status shows "completed" but no email is sent and workflow history displays error "Coercion warning: user or group does not have a valid e-mail address.".


Workflow action - Send an Email can resolve lookup of Person or Group field collected by Initiation Form only when "Return field as" is either "Login Name" or "Login Names, Semicolon Delimited".


When configure workflow action - Send an Email on workflow canvas in SharePoint Designer, if Data source is Person or Group from Initiation Form, set "Return field as" to either "Login Name" or "Login Names, Semicolon Delimited" depending on if you allow multiple groups.
