We are migrating from 2003 to 2010. Our 2003 mailbox policy deletes from the inbox only (not it's sub folders) but it appears that this cannot be accomplished in 2010 using retention policies. How is everyone getting around this? For example is are there powershell commands to do what I need and/or is there a process to move everything in the sub folders, say under the Inbox, to some other place?
