Many years ago, I worked for a contractor at a civil agency. Simply to make the email system function, we needed to keep retention at two or three weeks. The only persons for whom email was to be held were political appointees. What I saw was that they would take most of their last couple of weeks as vacation, and that there was almost never anything but department-wide announcements. It would have been possible to retrieve a point-in-time snapshot from a monthly backup, and that did happen a couple of times.
