Outlook Solutions

Visual Studio provides project templates you can use to create VSTO Add-ins for Microsoft Office Outlook. You can use VSTO Add-ins to automate Outlook, extend Outlook features, or customize the Outlook user interface (UI). For more information about VSTO Add-ins, see Architecture of VSTO Add-ins.

Applies to: The information in this topic applies to VSTO add-in projects for Outlook. For more information, see Features Available by Office Application and Project Type.

Create Outlook projects by using the Outlook Add-in project template in the New Project dialog box. This template includes required assembly references and project files.

For more information about how to create a VSTO Add-in project, see How to: Create Office Projects in Visual Studio. For more information about the project templates, see Office Project Templates Overview.

When you create an Outlook VSTO Add-in project, Visual Studio generates a class, called ThisAddIn, which is the foundation of your solution. This class provides a starting point for writing your code, and it also exposes the object model of Outlook to your VSTO Add-in.

For more information about the ThisAddIn class and other features you can use in a VSTO Add-in, see Programming VSTO Add-Ins.

The Outlook object model exposes many types that you can use to automate Outlook. These types enable you to write code to accomplish common tasks:

  • Programmatically create and send e-mail messages.

  • Send new meeting requests.

  • Search for items in Outlook folders.

For more information, see Outlook Object Model Overview.
