Form Events

Form events occur when something happens to an item displayed in a form, such as when it's saved or opened or when a user-defined action is started.

Most often, form events are handled by VBScript code within the form itself.

Some events can be cancelled. That is, your event handler can prevent Microsoft Outlook from performing the default action associated with the event. For example, you can write an event handler for the Forward event to prevent an item from being sent to recipients who are not on a list of approved recipients. Learn about canceling an event.

The following table lists the form events supported by Outlook.
