When you leave a group, you give up your access to the group inbox, calendar, OneNote notebook, and library. The only way to regain access is to rejoin the group.
When you unsubscribe from a group, you are still a member but no longer receive messages and calendar event notifications in your personal inbox. You'll have to go to the group inbox to see them.
