Outlook - delete permanently the email

Hi,
How do I do to delete permanently the email in MS Outlook 2003? For example
to delete permanently I use software as Eraser or MooO File Shredder, but
for the email?
If I delete the email form the bin they can they can be recuperated?

Thank you|
Giuseppe

All e-mail are records in a database (the .pst file).  When you "delete"
in Outlook, you do not delete at all.  Instead you *move* the item into
the Deleted Items folder.  To "permanently" delete (which really is not
deleting yet), you either:

- Delete an item from the Deleted Items folder.
- Or, use Shift+Del on an item in any folder.

What a permanent delete does is tag that item (its record) as "deleted".
Outlook will not display delete-tagged records.  Not until you compact
the database which commits a purge operation are delete-tagged records
physically removed from the database.  Because the delete-tagged records
get physically removed from the database is why a compact results in
reducing the size of that database.
