Actions display buttons that enable users to respond to a Microsoft Office Outlook item. For example, to respond to a mail item, users click the Reply, Reply to All, or Forward action buttons. Each of these actions creates a new mail item and populates the item's fields by using information from the original item.

You can create a custom action that opens any kind of Outlook item. For example, you can add a custom action that opens a new appointment or task item. Set the properties of a custom action or use custom code to populate the fields of the new item. Custom actions appear in the Custom Actions drop-down of an item that is open in an Outlook inspector window.

Adding Custom Actions to a Form Region

To add a custom action to a form region, use the Custom Actions dialog box. For more information, see How to: Add a Custom Action to an Outlook Form Region.

You can use the Custom Actions dialog box to specify a target form. A target form is the form that appears when the user executes the custom action.

You can also use the Custom Actions dialog box to specify how you want information from the original item to appear in the target form.

The following table describes the properties that are available in the Custom Actions dialog box.

Property	Description
AddressLike	Specifies how the target form will be addressed.

Customizing a Custom Action at Run Time

You can also add behavior to the custom action using code. For example, you can add code that takes the names of e-mail recipients and adds those names as attendees in a new appointment item. To do this, handle the CustomAction event of the Action object.
