Indeed, I worked for a financial company that had a 90-day default purge on all e-mails and chat. You could drag some e-mails to a retention folder ( limited in overall size ) but as far as I recall that only protected them for another finite span of time. Anything that needed a longer persistence had to be typed-up into a document and stored in Sharepoint, which was more manageable in terms of legal discovery than individual e-mails.
