Accept a shared reminder list invitation on iCloud.com

If you receive an email invitation to share a reminder list, you must accept the invitation to access the list.

Note: If you’re using upgraded reminders, you might not see all of your shared lists on iCloud.com. You also can’t manage sharing on the web. Use the Reminders app on a device with iOS 13, iPadOS, or macOS Catalina 10.15 to see and manage all your shared lists.

In the invitation email, click Join [list name].
In Reminders on iCloud.com, select the shared reminder list on the left, then click Join or Decline on the right.

After you accept an invitation, you can view and edit the shared list, and all participants will see the changes you make.

Note: Only a list’s owner can add or delete participants.
