This is really common.<p>Remember this was Exchange 2003&#x2F;2007. It sounds like they didn&#x27;t have an archiving solution, so most users would probably use Outlook rules or manual actions to move data from their 50&#x2F;100&#x2F;250MB mailbox to a PST file on their local PC. Once you do that, it&#x27;s up to the user to retain or not retain email. It&#x27;s not a criminal act to clean up old files.<p>The &quot;fishy&quot; part is a twist on this that isn&#x27;t in the news -- the use of external BlackBerry devices for stuff other than email. I&#x27;ll bet you that anything of a substantive nature that was communicated with Clinton was done via PIN messages on the Blackberry devices -- data which was never accessible by anyone other than those folks who had a means to capture and decrypt them in transit. The other thing with PIN messaging is that they were device based, so even if you intercept, you need to establish who had physical custody of the device.
