Keep reading to learn how to open and view address book calendars from the Outlook desktop application for Windows. This includes individuals' personal calendars, shared group calendars, and cohort calendars.

1. Open Outlook and navigate to your personal calendar.
2. From the top toolbar, click "Add Calendar" and then select "From Address Book...".
   
3. Search for the calendar you want. Then double-click the name of the person, group, or cohort to add it to the "Calendar" selection at the bottom of the window and click "OK".
   
   1. Note: If you're having trouble finding the desired calendar, change the Search option at the top to "All columns" and try your search again.
      
4. The selected calendar will open momentarily beside your personal calendar. If you don't see any meetings on the calendar at first, give it a minute to finish loading. [Note: Calendar permissions vary. You may have permission to view full appointment details for the selected calendar, or you may only be able to view free/busy information.]

Helpful Tips

• After you've opened a calendar once, it will appear in the left side panel under your "Shared Calendars" list (until you clear out your shared calendars). Just click the name to select it and open the calendar.
