How do you add dropdown calendars to custom Outlook forms?

[Guest]

I am trying to add a date reference to a form and would like to add a drop
down calendar to help select the date and input the information. This is
similar to the "Start Date" enteries on the default Task form. Any hints on
how to create this item?

Outlook itself does not include any date picker control (which, by the way,
is one reason why the first page of the appointment, journal, and task forms
is not editable). See http://www.outlookcode.com/d/datepick.htm for controls
you can add.
