An anonymous reader writes "In an age of litigation and costly discovery obligations, many organizations are embracing policies which call for the forced purging of e-mail in an attempt to limit the organization's exposure to legal risk. I work for a large organization which is about to begin destroying all e-mail older than 180 days. Normally, I would just duck the house-cleaning by archiving my own e-mail to hard-drive or a network folder, but we are a Microsoft shop and the Exchange e-mail server is configured to deny all attempts to copy data to an off-line personal folder (.PST file). The organization's policy unhelpfully recommends that 'really important' e-mails be saved as Word documents. Is anybody doing this right? What do Slashdot readers suggest for a large company that needs to balance legal risks against the daily information and communication needs of its staff?"
