Tip 868: Display a person's current age on their birthday event in Microsoft Outlook's Calendar

A frequent request is the ability to display a person's age on their birthday event in Outlook's calendar. We used to say "you can't" and pointed users to our custom form that displays a contact's current age.

We've since learned of a way to use custom fields to populate the subject field – one use of this is to add the age to the subject field of an appointment. Uses for this are not limited to displaying ages – the person who showed me the trick used it for the subject field of a task form.

It's not perfect and the contact form method might be a better solution for most people, in part because the age is always up-to-date. The age doesn't automatically update in the appointment form – you need to touch the subject field (adding a space to the subject will do it) to update the age.
