By default, Outlook 2007 only shows the tasks that are located in the main mailbox on the To-Do Bar. If you have tasks located in a PST file and want them to show up as well, follow this tech-recipe:
1. In the Navigation Pane, right-click on the personal folder containing the tasks.
2. Select Properties.
3. Check the Display reminders and tasks from this folder in the To-Do Bar checkbox.
4. Click OK.
