FormRegion Object (Outlook)
Represents a form region in an Outlook form.
The FormRegion object allows an add-in to add code behind a form region in a custom form to modify the appearance and behavior of the form region.
To obtain an instance of the FormRegion object, an add-in must implement the FormRegionStartup interface. Outlook allocates storage for the form region, instantiates an instance of the FormRegion object, and returns the FormRegion object in the GetFormRegionStorage method.
When the add-in closes the frame for the form region, the add-in must release the object for the form region.
