Earlier we mentioned the standard group names for calendars in the Navigation Pane: My Calendars, Other Calendars and People's Calendars. These group names can be changed. What's more, if you want to, you can create your own groups using names that you choose.
In the picture, we've shown the steps for creating a new group and moving a calendar to it:

In the
Navigation Pane, click
Add New Group.

Type a name for your group (here we've named the group "Sales Team").

Drag each calendar (one at a time) to the group. Here we're moving Mike Ray's calendar from
People's Calendars to the new
Sales Team group.
What are groups good for? They allow you to show or hide collections of calendars in the Navigation Pane. For example, suppose that you work with a sales team and each member of that team has shared a calendar with you. After you add a new group called Sales Team (as we did in the picture) and move all of the sales team's calendars into that group, you can collapse the group, which will temporarily hide the list of sales team calendars. But don't just take our word for it, try doing this for yourself in the practice session, which is coming up next.
