We'd like to continue to archive to keep our mailbox sizes down, but different managed folders will have different retention periods so we can't just do a blanket 90 day rule or whatever. So, an item gets archived in someone's Inbox, then they move they stub to a managed folder with a 7 year retention period on it that will be controlled by an Exchange 2007 rule. When Exchange purges the item I assume it is only going to delete the stub, leaving the item in the vault.
What is the best way to handle this?
