Restoring a Deleted Outlook folder from Dumpster?

Hello,

I see this issue a lot and want to confirm that folder restores from the dumpster are not possible.

We have tons of shared mailboxes in out environment (Exc 2010 Sp2 RU5) and with shared MB's, multiple users have permissions.

The mailbox is mapped and an additional mailbox or account in the users Outlook profile.  An user accidentally deletes a sub-folder on the shared mailbox.  Where does it actually go?

I cannot ever see the folder in Deleted Items or Recover Deleted Items.  We do not do brick level backups of Exchange (only DB's).

Is there a way to restore a folder in this scenario?

thanks!
