感謝@reedcopsey讓我們走上正軌......

檢索Outlook句柄的技巧是使用反射獲取活動窗口的標題（ Caption ）和FindWindow Win32 API以獲取活動窗口IntPtr句柄（ 檢查器，資源管理器等 ）。 靈感來自這篇MSDN論壇帖子 。 擁有活動窗口句柄后，您可以利用WindowInteropHelper來管理所有者關系。

檢索Outlook句柄（ 通過ActiveWindow ）

Window yourWPFWindow = new Window();
dynamic activeWindow = Globals.ThisAddIn.Application.ActiveWindow();
IntPtr outlookHwnd = new OfficeWin32Window(activeWindow).Handle;
WindowInteropHelper wih = new WindowInteropHelper(yourWPFWindow);
wih.Owner = outlookHwnd;
yourWPFWindow.Show();

OfficeWin32Window（ 幫助程序類 ）

///<summary>
/// This class retrieves the IWin32Window from the current active Office window.
/// This could be used to set the parent for Windows Forms and MessageBoxes.
///</summary>
///<example>
/// OfficeWin32Window parentWindow = new OfficeWin32Window (ThisAddIn.OutlookApplication.ActiveWindow ());   
/// MessageBox.Show (parentWindow, "This MessageBox doesn't go behind Outlook !!!", "Attention !", MessageBoxButtons.Ok , MessageBoxIcon.Question );
///</example>
public class OfficeWin32Window : IWin32Window
{

    ///<summary>
    /// The <b>FindWindow</b> method finds a window by it's classname and caption.
    ///</summary>
    ///<param name="lpClassName">The classname of the window (use Spy++)</param>
    ///<param name="lpWindowName">The Caption of the window.</param>
    ///<returns>Returns a valid window handle or 0.</returns>
    [DllImport("user32")]
    public static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

    #region IWin32Window Members

    ///<summary>
    /// This holds the window handle for the found Window.
    ///</summary>
    IntPtr _windowHandle = IntPtr.Zero;

    ///<summary>
    /// The <b>Handle</b> of the Outlook WindowObject.
    ///</summary>
    public IntPtr Handle
    {
        get { return _windowHandle; }
    }

    #endregion

    ///<summary>
    /// The <b>OfficeWin32Window</b> class could be used to get the parent IWin32Window for Windows.Forms and MessageBoxes.
    ///</summary>
    ///<param name="windowObject">The current WindowObject.</param>
    public OfficeWin32Window(object windowObject)
    {
        string caption = windowObject.GetType().InvokeMember("Caption", System.Reflection.BindingFlags.GetProperty, null, windowObject, null).ToString();

        // try to get the HWND ptr from the windowObject / could be an Inspector window or an explorer window
        _windowHandle = FindWindow("rctrl_renwnd32\0", caption);
    }
}

這可以通過WindowInteropHelper完成：

WindowInteropHelper wih = new WindowInteropHelper(yourWindow);
wih.Owner = outlookHwnd;
yourWindow.Show();
