Could someone advise me when sending an e-mail using the referenced how I
request a receipt? Thanks.

Go to Tools -> Accounts.
Open your e-mail account.
Under Options and Additional Headers, type 'Disposition-Notification-To'
under header and your address under value.

This will not always work, because some e-mail programs are configured not
to return receipts.

Submit other Outlook Express questions to the Outlook Express newsgroup:

replying as an e-mail.  Thanks so much!
