Setting up a calendar group
Click Calendar in the navigation bar at the top right of the screen
Right click on My Calendars on the left side of the screen and select New calendar group from the drop down list
Type in the name of the calendar on the left side of the screen and press enter on your keyboard
Add a user’s calendar into the calendar group
Right click on the new calendar group and select Open calendar from the drop down list
Search for the user’s calendar under From directory: and click Open
Each user in the group will show in a list under the calendar group name. Refer to Setting up the view of a shared calendar for more information on viewing someone else’s calendar and changing the colour of a shared calendar
