 Start Microsoft Visual Studio .NET. On the File menu, point to New, and then click Project. Click Visual Basic Projects under Project Types, and then click Console Application under Templates. By default, Module1.vb is created. Add a reference to the Microsoft Outlook 10.0 Object Library. To do this, follow these steps:  On the Project menu, click Add Reference. Click the COM tab.</li> Click Microsoft Outlook 10.0 Object Library, and then click Select</li> Click OK. If you are prompted to generate wrappers for the library that you selected, click Yes.</li></ol> </li>  In the Code window, replace the default code with the following code: Imports System.Reflection

Module Module1

Sub Main ' Create Outlook application. Dim oApp As Outlook.Application = New Outlook.Application ' Get Mapi NameSpace. Dim oNS As Outlook.NameSpace = oApp.GetNamespace(&quot;mapi&quot;) oNS.Logon(&quot;YourValidProfile&quot;, Missing.Value, False, True) ' TODO:

' Get Messages collection of Inbox. Dim oInbox As Outlook.MAPIFolder = oNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox) Dim oItems As Outlook.Items = oInbox.Items Console.WriteLine(&quot;Total : &quot; & oItems.Count)

' Get unread e-mail messages. oItems = oItems.Restrict(&quot;[Unread] = true&quot;) Console.WriteLine(&quot;Total Unread : &quot; & oItems.Count)

' Loop each unread message. Dim oMsg As Outlook.MailItem Dim i As Integer

For i = 1 To oItems.Count oMsg = oItems.Item(i)

Console.WriteLine(i) Console.WriteLine(oMsg.SenderName) Console.WriteLine(oMsg.Subject) Console.WriteLine(oMsg.ReceivedTime) Console.WriteLine(oMsg.Body) Console.WriteLine(&quot;---&quot;) Next

' Log off. oNS.Logoff

' Clean up. oApp = Nothing oNS = Nothing oItems = Nothing oMsg = Nothing End Sub
