You can view tasks in several different ways in Outlook. In addition to Task view, you can enable the To-Do bar to keep track of tasks while in other views. You can also sort your tasks while in Task view.
You can view tasks and other items flagged for follow-up while in other views, such as Mail or Calendar, by enabling the To-Do bar in those views.
Click the View tab on the ribbon.
Expand the Layout group, if necessary.
Click the To-Do Bar button.
Select Tasks.
A list of tasks and flagged items appears, organized by the date they are due.
When you enable the To-Do bar, it’s only enabled for the current view; meaning, if you enable it in Mail, it won’t appear in Calendar. You’ll need to enable it in each view separately.
To close the To-Do Bar, click the To-Do Bar button on the View tab and select Off.
In the Tasks view, you’ll find two separate lists of tasks: your To-Do list and your Tasks list.
Click the ellipsis button on the Navigation pane, if necessary.
Select Tasks.
In the Folder Pane, the My Tasks header will appear with two folders by default.
To-Do List will display your active tasks (those that haven’t been completed), as well as all the flagged items from your Mail, Calendar, and Contacts.
Tasks will display all of your standalone tasks, active and completed. Flagged items from Mail, Calendar, and Contacts will not be shown here.
