I'm getting the unread emails from outlook through this C# code. But now I want to find all read and mails that had given repliyes to the emails from outlook and delete them using C# code.

Microsoft.Office.Interop.Outlook.Application myApp = new Microsoft.Office.Interop.Outlook.ApplicationClass();
            Microsoft.Office.Interop.Outlook.NameSpace mapiNameSpace = myApp.GetNamespace("MAPI");
            Microsoft.Office.Interop.Outlook.MAPIFolder myContacts = mapiNameSpace.GetDefaultFolder(Microsoft.Office.Interop.Outlook.OlDefaultFolders.olFolderContacts);
 
            //login
            mapiNameSpace.Logon(null, null, false, false);
 
            mapiNameSpace.Logon("yourMailAddress", "password", Missing.Value, true);
 

            Microsoft.Office.Interop.Outlook.Items myItems = myContacts.Items;
 
           // Console.WriteLine("Total : ", myItems.Count);

            Microsoft.Office.Interop.Outlook.MAPIFolder myInbox = mapiNameSpace.GetDefaultFolder(Microsoft.Office.Interop.Outlook.OlDefaultFolders.olFolderInbox);
 
          //  Console.Write(myInbox.Name);

            Microsoft.Office.Interop.Outlook.Items inboxItems = myInbox.Items;
 
           // Console.WriteLine("Total : ", inboxItems.Count);

            Microsoft.Office.Interop.Outlook.Explorer myexp = myInbox.GetExplorer(false);
 
            mapiNameSpace.Logon("Profile", Missing.Value, false, true);
 

 
            if (myInbox.Items.Count > 0)
            {
                Microsoft.Office.Interop.Outlook.Items items = myInbox.Items;
                inboxItems = inboxItems.Restrict("[UnRead] = true");
                Console.WriteLine(string.Format("Total Unread message {0}:", inboxItems.Count));
                int x=0;
                foreach (Microsoft.Office.Interop.Outlook.MailItem item in inboxItems)
                {
                    Console.WriteLine("{0} unread mail from your inbox", ++x);
                    Console.WriteLine(string.Format("from:-       {0}", item.SenderName));
                    Console.WriteLine(string.Format("To:-         {0}", item.ReceivedByName));
                    Console.WriteLine(string.Format("Subject:-     {0}", item.Subject));
                    Console.WriteLine(string.Format("Message:-     {0}", item.Body));
                    System.Threading.Thread.Sleep(1000);
                }
                Console.ReadKey();
