This trick works on all versions of Outlook.
To change the number of weeks in the calendar view:
- Start with any Day/Week/Month view
- Drag the mouse over the dates in the navigation calendar to select up to 6 full weeks.
The display will change to the monthly grid format with large cells. The size of the cells are dependent on the size of your Outlook window and your screen resolution, along with the number of weeks selected.
The only downfall to this method is that the selection is not saved. The view reverts to 30 day view when you change folders.
Quick tip: Select the weeks in the To-Do Bar from any Outlook folder and you’ll jump to the Calendar folder with the weeks selected.
