History Logs provide history of all edits made to a Calendar by any Visitor to your Calendar with Edit Rights to the calendar. With the history log you can protect calendar data with real-time backups and recover a deleted calendar entry.
Use History Logs to see:
- Who changed a calendar entry
- What a calendar entry was before the change, and after the change
- When a calendar entry was changed
While you can see the Audit History Log for your entire calendar you can also look up the Audit History Log for individual events in your calendar. When you view the Audit History for an individual event you will still have all of the filters that are available when you view the Audit History for your entire calendar.
