A task request can be sent to anyone in your Outlook Address Book. If the user you send the request to also uses Outlook to manage their e-mail and tasks, they will be given a set of response options so you can easily track who will and will not be accepting your task.
The Assign Task Window can be accessed through the Task window by choosing the Assign Task command in the Manage Task group on the Task tab.
