Enterprise Plus, Education Plus
As your organization's administrator, you can use the security investigation tool to run searches related to Calendar log events, and to take action based on search results. From the investigation tool, 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.
