    Yes.
    
    A PST file works in a similar way to a database - when a message is
    deleted it is only flagged up as having been deleted, and is therefore
    not shown to the user.  The message is only truly deleted from within
    the PST file when either a) another message overwrites it, or b) when
    the user compacts the mailbox.
    
    In order to recover deleted messages from a PST file you need to do the
    following:
    
    1) Make a backup copy of the PST file being examined.
    2) Using a hex editor that you are familiar with replace bytes 7 to 13
    of the PST file with FF (they're usually set to 00).
    3) Run a tool called "scanpst", which is usually resident in C:\Program
    Files\Common Files\System\Mapi\1033 on a windows box.  It might not be
    in this directory, but should be installed by default.
    4) Open the PST file and any recoverable messages should have been recovered.
    
    Please note - it doesn't always work.
    
    Best of luck.
