Dear ComponentPro 
Following error is traced by using the IMAP Client in threads.

    

        

            

            
Unhandled Exception: ComponentPro.Net.Mail.ImapException: Previous operation has not finished yet.
            
   at ComponentPro.Net.Mail.ImapClient.AsyncBeginLck() in ComponentPro.UltimateMail\UltimateMail\Net.Imap\ImapClient.cs:line 4175
            
   at ComponentPro.Net.Mail.ImapClient.SendCommand(String command, Object[] parameters) in EmlMigrationForExchange\ComponentPro.UltimateMail\UltimateMail\Net.Imap\ImapClient.cs:line 2387
            
        
    



In my code snip, it try to create ImapClient object and then connect to the IMAP server in number of thread. 

    

        

            

            
private static void TestInThread(List<string> Users)
            
{
            
    foreach(string user in Users)
            
        System.Threading.ThreadPool.QueueUserWorkItem(ConnectToServer, user);
            
            

            
}

            private static void ConnectToServer(object asyncState)
            
{
            
    try
            
    {
            
        string[] user = Convert.ToString(asyncState).Split(new char[] { ',' });
            
 
            
        ComponentPro.Net.Mail.ImapClient imapClient = new ComponentPro.Net.Mail.ImapClient();
            
        imapClient.Connect("172.16.2.12", 143);
            
        imapClient.Authenticate(user[0], user[1]);
            
    }
            
    catch (Exception ex) { Console.WriteLine(ex);     }
            
}
            
        
    



Do you have any ideas for resolving?
