About Outlook forms
A form is an easy way to distribute and collect information electronically. For example, a form can be available for anyone to order supplies or post information in a public folder. Microsoft Outlook provides built-in forms such as the Message form to compose messages and the Contact form to enter information for a contact. If you have sent an e-mail message or created an appointment, you have used a form. Every Outlook item is based on a form.
You use the Outlook Forms design environment to create custom forms. Use a built-in form to leverage functionality from the item associated with it; for example, to include automatic name checking in a custom form, create it from a form based on an e-mail message. To modify a form, you can add and remove fields, controls, options, and tabs. A form can be saved as a file for use as a template or in another program or in a forms library to make the form available to others.
Developers can extend forms with Microsoft ActiveX controls and put World Wide Web pages on their forms by using the Web Browser control. Forms can be programmed by using Microsoft Visual Basic Scripting Edition (VBScript).
You cannot design Outlook forms in Microsoft Visual Basic or Visual Basic for Applications (VBA), although you can use forms created with the Microsoft Exchange Electronic Forms Designer (EFD) in Outlook. In order to use EFD, you must install an optional EFD run-time component that you can download from the Microsoft Office Download Center.
