I\'m trying to make a context menu for a hyperlink. It seems there are several contexts where hyperlink events can be intercepted -- at the moment I\'m interested in the contex
I had a similar problem and my solution looked like:
public void OnCustomHyperlinkMenuClick(IRibbonControl control)
{
    Explorer explorer = control.Context as Explorer;
    if (explorer != null)
    {
        Document document = explorer.ActiveInlineResponseWordEditor;
        //Note from asker: above line throws a COM Exception ("The operation failed")
        if (document != null && document.Windows != null && document.Windows.Count > 0)
        {
            Microsoft.Office.Interop.Word.Selection selection = document.Windows[1].Selection;
            if (selection != null && selection.Hyperlinks != null && selection.Hyperlinks.Count > 0)
            {
                Hyperlink hyperlink = selection.Hyperlinks[1];
                string hyperlinkUrl = hyperlink.Address;
                DoSomethingWithUrl(hyperlinkUrl);
            }
        }
    }
}
You will need to add a reference to the word interop assembly "Microsoft.Office.Interop.Word.dll" to your project.
