We are currently running Exchange 2010 SP1 and have about 220 email accounts. Because of record retention laws we cannot have email automatically purged. We recently have been approved to purge all email prior to 2011 but I am now sure how to accomplish this. I need to purge all email for all accounts (inbox and sub folders, sent and deleted items).
I've looked into the Retention Policy Tags but I'm not sure how to set a policy that covers the inbox, sent and deleted items.
Any direction would be greatly appreciated.
