How to choose Mail (Mapi) when clicking "Export" in the Report Viewer

Question

I'm using .net 2008 and CR 2008 for reporting.
In a form I placed the ReportViewer.
Everything works fine.
Here my problem: When I click "Export" in the Viewer I get the File-Dialog with Excel, Word, PDF.
But I'm missing the Dialog where I can choose MAPI (Microsoft Mail) as destination.
To illustrate, how I implemented the CR 2008 in our application:
    Public Sub ReportStarten()
        Dim l As Integer
        Dim Cmd As System.Data.SqlClient.SqlCommand = Nothing
        Dim Reader As System.Data.SqlClient.SqlDataReader = Nothing
        Dim ReportDataTable As System.Data.DataTable
        Dim SqlConn As New System.Data.SqlClient.SqlConnection()
        Dim ReportFenster As New ReportForm
        If Me._DruckVorschau Then
            ReportFenster.Text = Me.Reporttitel
            ReportFenster.Show()
            ReportFenster.WindowState = Windows.Forms.FormWindowState.Maximized
        End If
        'Diese Selektion wird im Report selbst berücksichtigt
        Me._ReportRpt.DataDefinition.RecordSelectionFormula = Me._RecordSelection
        l = 0
        Dim myTables As CrystalDecisions.CrystalReports.Engine.Tables = Me._ReportRpt.Database.Tables
        For Each myTable As CrystalDecisions.CrystalReports.Engine.Table In myTables
            SqlConn.ConnectionString = Me._ConnectionString
            SqlConn.Open()
            Cmd = New System.Data.SqlClient.SqlCommand(Me._TableSource(l))
            Cmd.Connection = SqlConn
            Reader = Cmd.ExecuteReader(CommandBehavior.CloseConnection)
            ReportDataTable = New System.Data.DataTable()
            ReportDataTable.Load(Reader)
            myTable.SetDataSource(ReportDataTable)
            l += 1
        Next
        If Me._DruckVorschau Then
            'Vorschau
            ReportFenster.CrystalReportViewer.ReportSource = Me._ReportRpt
        Else
            'Sofortdruck
            Me._ReportRpt.PrintOptions.PrinterName = Me._DruckerName
            Me._ReportRpt.PrintToPrinter(1, False, 0, 0)
        End If

The wiki (http://social.technet.microsoft.com/wiki/) is probably a better place for this.
