Can email notifications be sent again to someone who was already notified?

Yes, your administrator can select Resend Email Notification from the Actions menu in the Transaction Console work area to resend emails to the current workflow task assignee. If you have access to the work area, you can do so yourself.

For example, if a task has been pending for a while, maybe the assignee didn’t see the original email notification, or had accidentally deleted it. Or, the original email body wasn’t formed correctly. For any of these cases, and more, resending the email can help move the approval along.
