The calendar administrator is any authorized person who has administrator access to the calendar. The calendar administrator can access all calendar settings and has full control over the calendar.
The settings include important abilities:
- The ability to manage calendar sharing: in the Settings, you can add, modify, remove, and set permissions for account users. You can also create, enable, disable, modify, and/or delete any shareable calendar links.
- The ability to add, modify, or delete any sub-calendars and organize sub-calendars in folders.
- The ability to manage notifications: in the Settings, you can see all notification subscriptions (including email notifications, daily agenda emails, and Slack notifications) and modify or delete subscriptions as needed.
- The ability to alter calendar settings, such as the time zone, default language, admin email, and whether to enable (or disable) features such as event sharing, iCal feeds, and more.
- The ability to downgrade, upgrade, or renew a calendar subscription or delete the calendar completely.
Administrator access to the calendar should be carefully protected and only provided to people with the correct authorization and understanding. Administrator privileges should only be assigned to an authorized person.
Change the calendar administrator
If the calendar administrator leaves your organization, ensure that you maintain calendar security by revoking admin-level calendar access immediately. To do so, go to the calendar Settings > Sharing, find the previous administrator in the list of users, click the Edit icon, and check “No” in the Administration section.
If you accidentally share a link with administrator level access, you can delete it, deactivate it, change the permissions, or add a password in order to prevent unauthorized administrator access to your calendar. See more details here.
