A user had a question:
I have the calendar and tasks in the to-do bar on the side of my messages. The calendar uses the month view. Can I change this to a week view?
No, sorry you cannot change the calendar layout in the To-Do Bar or Peek.
Appointments scheduled within the next seven days are shown under the calendar thumbnail. If you select another date, you’ll see appointments for the next seven days from that date forward.
You can change the view on the Task list or Task peek.
