Release2026-10-05

Google Workspace now ties secondary calendars to their owner’s account lifecycle. Deleting a user account deletes their secondary calendars. Suspending a user suspends their secondary calendars. This matches the behavior of primary calendars. Ownership must be transferred to preserve a secondary calendar. Admins can transfer calendars in the admin console or via the Calendar API. End users can transfer calendars in Calendar Settings. The rollout starts on October 5, 2026 for all Workspace customers.
