Main code：
        static void Main(string[] args)
        {
            try
            {

                using (var msn = new jks.msn.MSNTool("begtostudy@gmail.com", "****"))
                {
                    msn.ToContact = "begtostudy@hotmail.com";
                    msn.SendMsg("Finished");
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex);
            }
        }

The receiver can't receive the message sometimes, but sometimes can.

Would you please provide a trace log of the library when it can't receive 
messages?

Can you login with the official WLM and check if the same thing happens? It 
seems that you are not receiving anything from the server.

No problems in WLM and the example of the project.
Only for my program, others can't receive the message sometimes.

I want to transform the asynchronous to synchronous program for avoiding the 
main thread closed before the message is sent by MSNPSharp.

Then this is not in our support scope...
