How can I use Outlook MAPI to read inbox emails in C#?

First, ensure the Outlook client is installed and logged in. Then create a C# console application and reference the `Microsoft.Office.Interop.Outlook.dll` that matches your Outlook version. Use code like `Application app = new Application(); NameSpace ns = app.GetNamespace("MAPI"); MAPIFolder inbox = ns.GetDefaultFolder(OlDefaultFolders.olFolderInbox);` to obtain the inbox and iterate over its `Items` to access `MailItem` properties such as Subject, SenderName, Body, and Attachments. A full example is provided in the Outlook MAPI Development Guide.
