In Outlook for the web you use Import calendar to add another person's calendar to your list. You can also add a calendar from a file or from the web, like a subscribed calendar.

When you create an additional calendar, often referred to as a secondary calendar, you might add events to that calendar and expect those events to also impact your availability. However, when others view your availability using the Scheduling Assistant, the secondary calendar events aren’t shown. This behavior is by design. Only events on your primary calendar impact your availability.
