Can Exchange 2010 mailbox that has expired retention be recovered?

I have a request to attempt discovery of a mailbox on Exchange 2010. The mailbox in question is past the shelf of the retention policy by two years. nothing shows in the disconnected list, and from the shell running a query to find the mailbox with the DB name and username as input filters returns nothing. Is there any way to do this from Exchange or a third party utility?

Your only hope is to find some sort of backup (e.g. someone exported the mailbox to PST before deleting it from Exchange, you find a 2 year-old backup tape somewhere, find a copy lurking as an OST on an old hard drive, etc.). When a mailbox is "deleted" from Exchange it hangs around in limbo for whatever your system's retention period is set to then, after retention expires, the records comprising the mailbox are marked as free space and Exchange will begin writing new data to those rows in the edb. After two years, there is virtually zero chance of recovery...at least not by poking around for it in Exchange. Even the most sophisticated third-party recovery tool wouldn't be able to recover the mailbox intact after that long a period.

Point well taken. I actually DID find an old MDB and in the process of looking for it. Thank you for the confirmation and suggestion.
