Depending on your Google Workspace edition, you might have access to the security investigation tool, which has more advanced features. For example, super admins can identify, triage, and take action on security and privacy issues. Learn more

As your organization's administrator, you can run searches and take action on security issues related to Calendar log events. For example, you can view a record of actions to track changes to calendars, events, and subscriptions. You can also track the email notifications associated with these actions. This information is helpful when you troubleshoot issues or when your users notice discrepancies or unexpected changes to their calendars, shared calendars, or specific calendar events. Log entries usually appear within one half-hour of the user action.
