Most orgs that I see restrict PST files altogether for security reasons. A policy of 7 years for all data is fairly common and usable .. people need the data to do their jobs.
Martin MVP Exchange From: Mike Tellson [mailto:micha...@colonialsavings.com] Sent: Wednesday, April 28, 2010 2:32 PM To: MS-Exchange Admin Issues Subject: Retention Policy Management is considering changing what the current email retention policy parameters are. Our current policy is to purge all messages older than X days, but we do not restrict the use of PST files. This policy has encouraged most employees create PST files. This effectively has made the retention policy irrelevant. We are considering importing all PST data into an email archive product (yet to be purchased) and disabling the ability to use PST files. Because so many users do not comply with the existing policy we will probably change the policy to something that the user base is more apt to adhere to. What are your retention policies set to? What is the reason why you chose the settings you have in place?
