We currently have a SharePoint 2013 farm, with an Active Directory User Profile sync, where we store public documents by department, in their own site collections by department, as well as personal documents in their own MySite Document Library.
When an employee leaves the company, we have been told that the documents of the former employee would be under the control of the Manager listed in Active Directory, after their account is deleted.
Is this true? My concern, especially with the MySite documents, since they are in their own site collection would be lost after the cleanup removes the former employee's site.
Is there a best practice to ensure documents owned by a former employee are not purged?
