As I understand it, the policy is that only emails that should be permanent, official records are supposed to be saved - and the judgement of what those are is left up to the individual employee. If you're someone investigating that employee, you're not going to trust that judgment. You'd want to see all of the employee's emails - even ones about lunch plans and carpool arrangements. Not to mention going through thousands of of paper emails is likely to be even more labor-intensive than the electronic search and review so far.
