You select a source form if you have chosen either the Mailbox Folder Form or Public Folder Form option. If you had selected a form in the Script Director folder tree, a form will be pre-selected for you. If no form is pre-selected, check the Install from Template box and then click the Select Form Template button to select an Outlook Form Template (.oft) in the file system. You will see the form display name, message class, version and form number, and any comments associated with the form definition.
Click Next once you have selected the source form.
