If you send emails, you might want to know that you can prepare an email and then delay the "send" so that you can think it over, maybe edit the draft, or simply send it when you want.
You could use this option to prepare an email saying "Happy Birthday"! and then delay the send until the appropriate date. That way you will never "forget" a friend's birthday again--well, almost. At least it won't look like you forgot, even if you did.
Delay sending an e-mail message
• From within the e-mail, click on the Options ribbon / More Options section / Delay Deliveries.
• Select the Do not deliver before and select date and time.
WAH-LAH You're a genius on Outlook or at least you'll look like one :)
