    Outlook.MailItem cItem = mail.copy();
    //
    cItem = (Outlook.MailItem)cItem.Move((Outlook.MAPIFolder)
    this.Application.ActiveExplorer().Session.GetDefaultFolder
    (Outlook.OlDefaultFolders.olFolderJunk));

You are in the ItemAdd event handler. Try to store the item's entry id in a variable or a list and start a timer (use the one from the Forms namespace). When the time fires, you will be out of the event handler and should be able to call MailItem.Move.
