    I think I misused the term "tombstoned" and thereby insinuated that the
    email would be kept in a deleted, yet intact, state for a pre-determined
    amount of time.  That's not what I meant and that isn't what happens as
    you point out.  Compaction will immediately remove unallocated space
    from a PST including deleted email assuming the PST file meets the
    minimum size requirements for compaction.  Compaction will also leave a
    small amount free space, 16K or 4% of the file size before compaction,
    whichever is greater.  That 4% can leave a lot behind depending on the
    file size.  Compaction can be run manually or it can be set as an
    automatic process that runs when the CPU isn't heavily utilized.  If a
    user doesn't set either, it is never compacted as far as I can tell.

    I don't think this is correct.
    If you just delete e-mail from a PST, it will remain in it (even if try
    to permanently delete e-mail with shift+delete so you don't just move it
    to Deleted Items folder).
    However, it will be actually removed when Outlook does PST folder
    compaction. I'm not sure how often Outlook does that process but you can
    do it manually by right clicking on your PST folder in Outlook and then
    go to Properties, Advance.
    
    Best regards,
