In visual studio on project select add new item. Choose Ribbon(XML).

add following to XML file:

<contextMenus>
    <contextMenu idMso="ContextMenuMailItem">
     <menu id="ArcIT" label="ArcIT">
       <button id="MyContextMenuMailItem"
           label="ContextMenuMailItem"
           onAction="OnMyButtonClick"/>
     </menu >
   </contextMenu>
  </contextMenus>

in ribbon.cs class add following method

public void OnMyButtonClick(Office.IRibbonControl control)
    {


        if (control.Context is Outlook.Selection)
        {
            Outlook.Selection sel = control.Context as Outlook.Selection;
            Outlook.MailItem mail = sel[1];
            MessageBox.Show(mail.Subject.ToString());

        }
    }

method has to be public. This method shows a box with subject from the mail u right clicked.
