To be notified when your outgoing messages are received
You can set up Outlook Express to display a receipt for e-mail you send. The
receipt is sent when the message recipient has displayed your message. This is
useful when you are sending time-critical information, or any time you want
confirmation that your message has been received.
To request a receipt for individual messages
a.. In the new message window, on the Tools menu, click Request Read Receipt.
To request a receipt for all messages
1.. On the Tools menu, click Options.
2.. On the Receipts tab, select the Request a read receipt for all sent
messages check box.
Note
a.. Message recipients can choose not to send read receipts, even when they
are requested. If you do not want to send receipts, on the Tools menu, click
Options. On the Receipts tab, select a Returning Read Receipts option.
