I have to agree. We can all assume that exchange is being used. In an organization as large as the IRS, they need tons of standardization. Since things are standardized, the chances of data only being stored on a person local outlook cache is crapppppppppp. We all know that the exchange server had snap shots taken and that they had some sort of email archiving set up. Further, I think there emails are not only stored in some back up somewhere but I bet we can find proof of any malice. Reasons behind it? It's digital. There is no way we have zero proof. If we launch a third party investigation, they'll find it all.
