Exchange/Outlook 2007: Emails being deleted after 90 days

hi there,

is there anyway to check from Outlook 2007 or OWA 2007 that the email system administrator has enabled messaging records management (MRM) for the user's mailbox?

He's been complaining that his emails that are older than 90 days are being deleted. I've check his autoarchive settings but it is was not enabled. I couldn't find any .PST files on his PC too.

Help please!!

Thanks!!
