The Journal folder in Outlook lets you keep track of lots of different types of events that don’t really fit into the other Outlook folders. For example, you can use the Journal folder to keep notes, to track duration of phone calls, to track the time you spend working on particular documents, and to note other events. In fact, Outlook can automatically track your document usage in the Journal folder if you direct it to do so.
Outlook doesn’t show the Journal folder on the Navigation pane by default. You can open the Journal folder from the folder list. Or click Configure Buttons on the bottom right of the Navigation pane and then choose Navigation Pane Options. Place a check mark beside the Journal folder and click OK. The Journal folder then appears on the Navigation pane.
