Open a Shared Calendar

1. Get logged in to Office.com and open your calendar
2. At the top Click "Add Calendar" from Directory
3. Start typing what you think it is called (Olympu...) then at the bottom click "Search Directory".  This should bring up a list of e-mails and calendars!
4. Pick the calendar you need.  The calendar or room icon looks like a door and has an e-mail address.
5. That will add it to your "Other Calendars" tab on your Outlook Calendar page.
