If you're looking to view someone else's shared calendar or a general shared calendar (like a conference room calendar), follow these steps:
- Navigate to Calendar view in Outlook
- Click Open Calendar > Open Shared Calendar
- Alternatively, you can click From Address Book..., find the email address in the Global Address List, then click OK.
- Type in the email address of the calendar and click OK.
Depending on your permissions for the calendar, you may see all details, very few details, or not be able to access the calendar at all.
