So, someone has arranged to share calendars with you. Hooray! But what do you do now? Again, we look to the useful Navigation Pane. When you're viewing your calendar, you'll see a link in that pane called Open a Shared Calendar.
To open the shared calendar, you would click this link, click the Name button, and select or type the name for the person sharing with you. Right away, you'd see the name listed under Other Calendars.
