How can I read out the receiver and sender in the Reading Pane in Outlook with VB.net or C#

Question

How can I read out the receiver and sender in the Reading Pane in Outlook with VB.net or C#. It goes in a new window in which a new mail is created with

objOL = CreateObject ("Outlook.Application")
MsgBox ("objOL.ActiveInspector.CurrentItem.To:" & objOL.ActiveInspector.CurrentItem.To

It doesn't work in the reading pane (docked window).

Thsi test in c# works for me on an opened Outlook instance (Outlook 2016, Windows 10) =>

Microsoft.Office.Interop.Outlook.Application oOutlookApp= null;
if (Process.GetProcessesByName("outlook").Count() > 0)
{
    oOutlookApp = Marshal.GetActiveObject("Outlook.Application") as Microsoft.Office.Interop.Outlook.Application;
    if (oOutlookApp != null)
    {
        Microsoft.Office.Interop.Outlook.MAPIFolder selectedFolder = oOutlookApp.ActiveExplorer().CurrentFolder;
        if (oOutlookApp.ActiveExplorer().Selection.Count > 0)
        {
            Object selObject = oOutlookApp.ActiveExplorer().Selection[1];
            if (selObject is Microsoft.Office.Interop.Outlook.MailItem)
            {
                Microsoft.Office.Interop.Outlook.MailItem mailItem = (selObject as Microsoft.Office.Interop.Outlook.MailItem);
                string sSender = mailItem.SenderName;
                string sTo = mailItem.To;
                System.Windows.Forms.MessageBox.Show("Sender : " + sSender + Environment.NewLine + "To : "  + sTo + Environment.NewLine, "Information", MessageBoxButtons.OK, MessageBoxIcon.Information);
            }
        }
    }
}

Hello Castorix31,

how must I change your Code form above. I try it with oOutlookApp.ActiveExplorer().ActiveInlineResponse; but I receive everytimes errors. Must I use the code var resp = oOutlookApp.ActiveExplorer().ActiveInlineResponse; in connection with oOutlookApp = Marshal.GetActiveObject("Outlook.Application") as Microsoft.Office.Interop.Outlook.Application;?
Sorry, I am not the specialist in c#.

But my problem that I can't read receiver and sender in the Reading Pane in Outlook with VB.net or C# is not solved. In the appendix I am attaching a screenshot in which I present the problem again. In the picture you see the red arrows in the reading pane/area from outlook. The reading pane/area open when you click in the reading pane/area on the button Reply (I think that is the Name from the button in an English MS-Outlook). I want read the Adress from Sender (Von) and the recipient/receiver(An) in the reading pane/area. If you click the Reply button in the reading area, no new window will open. The answer mail is answered directly in the main Outlook window. I want know, what is the refrence from the reading pane/area in Visual Studio?

Hello Castorix31,

thank you very much for your tip with search for "TYPE_E_CANTLOADLIBRARY" interop. I found, that the reason can be, that the MS-Office is corrupt, it was true, I repair my MS-Office an now it's run :).
