The left pane next to the navigation bar is the tasks tree. This tree provides a hierarchy view showing how the tasks are organized. There are two types of tasks:
Personal Tasks: Your personal tasks, which only you can access and modify.
Group Tasks: Tasks which are accessed and modified by the members of a group.
From the My Tasks page, click the Personal folder to view your personal tasks.
Click the Groups folder to view listings of only those contacts that are present in your groups folder.
