Because calendars have a specified mandatory retention period, action must be taken to preserve these records (including metadata) when an employee leaves a department or the university. In Outlook, one way to accomplish this is to export a copy of the employee’s calendar to a PST file.
The retention period for calendars is 1 year after the end of the calendar year. This can be a difficult retention to implement unless you are very familiar with how your email client works. Learn how to clean up your Outlook calendar in this resource.
