In the properties of a new email message, you can use the
Do not deliver before�option to delay the delivery of a new message. This delay period can range from a minutes to several weeks. When the message is eventually delivered, the recipient still sees the time at which the message was�
composed�by the client, and not the time the message actually left the Outbox.�
When Outlook is connected in Online mode to an Exchange Server mailbox, the messages are directly submitted to the Exchange mailbox. Therefore, the "Sent�Time" time stamp information for that message is the time�that the message was submitted to the mailbox on Exchange, not the actual�time that it was delivered to the recipient.
