I am helping a friend with a computer problem. She is
running Windows XP Pro. Within Outlook 2003, she is
unable to delete, permanently delete, or move files from
her Sent box. She receives the error "The messaging
interface has returned an unknown error. If the problem
persists, restart Outlook."

She has tried running her Inbox Repair Tool, as well as
Scan disk.

Anyone have any ideas on how to fix this problem?

Try creating a new mail profile under control panel->mail icon->show
profiles.

If I were in her shoes, I'd create a new PST, make it my default PST and
move items from the old PST to the new, skipping the old Sent Items folder.
Or, I'd just leave the old items where they were (except for my Contacts)
and just continue from there.
