The Microsoft.Office.Tools.Outlook namespace contains a set of classes and interfaces that enable you to create form regions that customize Microsoft Office Outlook forms.
Form regions are represented by the FormRegionControl and ImportedFormRegion classes. When you add an Outlook Form Region item to an Outlook add-in project, Visual Studio Tools for Office adds a class to the project that inherits from one of these two classes.
If you import a form region into an Outlook add-in project by using the New Outlook Form Region wizard, Visual Studio Tools for Office creates a form region class that inherits from ImportedFormRegion.
If you select Design a new form region on the first page of the New Outlook Form Region wizard, Visual Studio Tools for Office adds a form region class that inherits from FormRegionControl.
In both cases, Visual Studio Tools for Office adds a form region factory class to the project that implements the IFormRegionFactory interface. The form region factory class is responsible for creating new instances of the form region.
The Microsoft.Office.Tools.Outlook namespace also contains classes and attributes that represent the type of form region, the unique name of the form region, the properties that define how the form region appears in Outlook, and the message class names of Outlook items with which the form region is associated.
