Outlook drag and drop .msg error

Question

I have the below code handling my Drag and Drop of an email from outlook into a forms textbox. The problem i am having is after the code works the drag and drop the instance of outlook visually freezes. i assume i need to release outlook in some way but i am not sure how.

Private Sub frm_DragDrop(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles tbAppEmail.DragDrop
    tbAppEmail.Text = String.Empty
    Try

        If e.Data.GetDataPresent(DataFormats.FileDrop) Then
            'supports a drop of a file from Windows Explorer

            'Removed for visibility 


        ElseIf e.Data.GetDataPresent("FileGroupDescriptor") Then
            'supports a drop of a Outlook message

            'Dim objMI As Object - if you want to do late-binding
            Dim objMI As Microsoft.Office.Interop.Outlook.MailItem

            For Each objMI In objOL.ActiveExplorer.Selection()
                'hardcode a destination path for testing
                Dim strFile As String = _
                            IO.Path.Combine("\\ud1.utility\GSA\LWREPPLA\Databases_Dont_Touch\RTTEmails", _
                                            (objMI.Subject + ".msg").Replace(":", ""))
                tbAppEmail.Text += strFile + Environment.NewLine
                objMI.SaveAs(strFile)
            Next
        End If
        'tbAppEmail.Text = String.Empty

    Catch ex As Exception
        tbAppEmail.Text = "An error occured in the drop event" + Environment.NewLine + ex.ToString
    End Try
End Sub

Try not to use the Outlook Object Model from your drop handler. Note that the FileGroupDescriptor will contains the messages in the MSG format.

Not sure how i would go about using the FileGroupDescriptor to get the .msg file – Lickrob Mar 07 '16 at 11:58
