add another person’s calendar to my calendar view
If you receive an invitation to share someone else’s calendar, you can select the link in the invitation to add their calendar to your calendar view.
You also can go your Calendar to add other people’s calendars to your view.
Right-click in the navigation pane where you see Other calendars. Or, touch and hold if you’re using a touch device.
Choose Open calendar.
To add a calendar that belongs to someone in your organization, in the From directory box, type their name. The From directory box works like the To box in a new email message. After you type the name, choose Open to add the calendar.
To add a calendar from outside your organization, in the Internet calendar box type the URL, and then choose Open. The URL probably ends with the .ics file extension.
After you add another calendar, you can select it to add it to, or remove it from, your calendar view. Or use the context menu to rename it, change its color, or delete it from your view.
