Add‑in Express™ for Outlook® Express and Microsoft® .NET is a premier Rapid Application Development (RAD) framework designed for creating Microsoft Outlook Express and Windows Mail extensions using Microsoft Visual Studio .NET 2003, 2005, and 2008. It fully supports Outlook Express 6.x and Windows Mail on Windows Vista, providing a unified, Outlook‑like extensibility model that enables developers to build powerful, managed, isolated and secure plug‑ins. Developed in C#, the framework directly supports VB.NET, C#, C++, and RemObjects Chrome across all commercial Visual Studio editions, including Standard and Professional, making professional‑grade OE development widely accessible.

Features

• Unified extensibility model: Reflects the Microsoft Outlook Object Model into Outlook Express, providing Outlook‑like objects such as Application, Folder, MailItem, Explorer, Inspector, Attachment, as well as events like NewMail, SelectionChange, ItemAdd and FolderSwitch.
• GUI customization: Add custom menu items to the main OE menu and Inspector menus. Create custom toolbars for the main Outlook Express window and mail windows. Use pop‑up, dropdown, split buttons and separators on OE toolbars. Develop Preview Pane regions, view regions, form regions, Folder List regions, Contacts Pane regions and Outlook Bar regions.
• Version‑neutral OE development: Write your OE plug‑in once and run it seamlessly on Outlook Express 6 (Windows 2000/XP) and Windows Mail on Vista without compatibility issues.
• Isolation via ADX Loader: A dedicated loader isolates each add‑in into its own AppDomain. Add‑ins become strongly typed, managed, secure and easily deployable.
• Efficient project templates: Built‑in project templates centralize all technology‑specific modules and components to accelerate plugin development.
• Advanced form and view regions: First tool on the market that embeds your custom forms into OE views, mail compose windows, mail read windows and the main application UI.
• Visual designers instead of routine coding: Customize menus, toolbars, events and GUI elements using designers rather than manual code.
• Component‑centric programming model: Components handle complex OE automation tasks, making add‑ins feature‑rich with far less code.
• Deployment support: Automatic creation of a Visual Studio‑based setup project for your OE extension.

Benefits

• Faster development: Develop powerful OE extensions significantly faster using RAD methodologies.
• Familiar programming model: Enjoy a familiar Outlook‑like object model when working with Outlook Express.
• Secure, isolated add‑ins: Build isolated, secure and version‑independent add‑ins.
• Reduced manual coding: Drastically reduce manual coding thanks to visual designers and ready‑made components.
• Cross‑version compatibility: Ensure compatibility across Outlook Express 6.x and Windows Mail on Vista.
• Reliable deployment: Easily deploy fully managed OE extensions using the built‑in setup projects.
