Region Kind Constants Enum
Contains constants that specify whether the form region that a form region factory creates is based on a user control or an Outlook Form Storage (.ofs) file.
public enum FormRegionKindConstants

Specifies that the form region is based on a user control.
If you create a form region in code, return one of these constants in the Kind property of the form region factory class. A form region factory class is any class that you create that implements IFormRegionFactory.
The add-in gets the value of the Kind property to determine what type of form region to create.
