I have no interest in setting up MRM. We have an archiver appliance that keeps all emails - not just what the user thinks is important.
I simply want to reduce the size of our live mailbox databases now that all emails are duplicated and are accessible from the archiver.
I would like to simply set Exchange to delete all items older than 2 years in all mailboxes and keep it that way. I haven't found a way to do it by date/time only by size.
