By default, Outlook’s To-Do Bar only displays the current month’s calendar. While this is helpful, it does little for providing a quick reference for looking at future months. You can configure the To-Do Bar to display multiple months and have a quick view of not only the current month, but the next few months as well.
1. Open Outlook.
2. Go to the Menu.
3. Click View, mouseover To-Do Bar and select Options.
4. Beneath the Show Date Navigator checkbox, use the designated textbox to input the number of month rows you wish to display in your To-Do Bar (1-9, maximum viewable number will depend on your screen size).
5. Click OK.
