Remarks
By default, a custom message class inherits all the form region associations of the base message class. For example, a message class named IPM.Task.Contoso derives from IPM.Task. Therefore, IPM.Task.Contoso inherits the form region associations of IPM.Task.
If you do not want the form region to be associated with any derived message classes, set the ExactMessageClass property of the form region to true. For example, if you associate an adjoining form region with IPM.Task and set the ExactMessageClass property to true, the form region will only be appended to the bottom of a standard task form. The form region will not be appended to the bottom of any customized versions of a standard task form.
