Remove duplicate calendars from your computer

Follow the steps for your operating system.

Mac

To hide a calendar stored on your Mac, follow these steps: 

  1. Open Calendar. If you don't see a list of your calendars, click the Calendars button in the upper-left corner.
  2. Go to the section named On My Mac. 
  3. Compare the events in On My Mac to the events on your iCloud calendars. 
  4. If your calendars in iCloud show all of your events and the calendars on your Mac show only duplicates, hide the calendars on your Mac. To hide a calendar, uncheck its box in the section called On My Mac.  

If you choose to delete calendars on your Mac, delete only those in the On My Mac section. Don't delete calendars on your Mac in any other section, like iCloud, Subscriptions, Other, or other calendar services.

To delete calendars on your Mac, follow these steps: 

  1. Make a copy of your iCloud calendar data.
  2. In the On My Mac section, click the calendar you'd like to delete. 
  3. Choose Edit > Delete.

Windows PC

To hide a calendar on your PC, follow these steps:

  1. Open Outlook and click Calendar. If you can't see your list of calendars, expand the pane: Click the right arrow button above the Navigation Pane button (Outlook 2007), Folders button (Outlook 2010), or All Folders button (Outlook 2013 and later).
  2. Go to the section named My Calendars. 
  3. Compare your events in My Calendars to the events on your iCloud calendars. 
  4. If your calendars in iCloud show all of your events, and the calendars on your PC show only duplicates, hide the calendars on your PC. If some events on your PC aren't in iCloud, try manually importing your events to iCloud. Open iCloud for Windows, deselect the “Mail, Contacts, Calendars, and Tasks” checkbox, and click Apply. Select the checkbox again and click Apply.

To delete calendars on your PC instead of hiding them, follow these steps:

  1. Make a copy of your iCloud calendar data.
  2. In My Calendars on your PC, right-click the calendar you'd like to delete and choose Delete Calendar. Outlook won't let you  delete the default Calendar, but you should be able to remove other calendars that you have permission to delete.
