Java 接收OutLook 微软邮箱邮件

首先引入maven依赖

上述代码直接搜索的是收件箱中的邮件，其实还是指定目录进行获取邮件

  public static void scanMail(String emailAddress, String password) throws Exception {
        ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
        String name = emailAddress.split("@", 2)[0];
        ExchangeCredentials credentials =
                new WebCredentials(name, password, "msxf");
        service.setCredentials(credentials);

        service.setUrl(new URI("https://mail.xxxx.com/ews/Exchange.asmx"));
//        读取多少封邮件
        ItemView view = new ItemView(100);
//        读取文件夹（即每页显示多少个,最终展示几页） 这里与常见的分页类似,因此此值可以设置为较大值,来避免分页,当然根据情况来定
        FolderView folderView = new FolderView(100);
//        搜索文件夹,第一个参数为父文件夹,这里设置为了收件箱,因为收件箱是本来就有的文件夹,同样的参考WellKnownFolderName枚举
        FindFoldersResults foldersResults = service.findFolders(WellKnownFolderName.Inbox, folderView);
        System.out.println("文件夹总数量：" + foldersResults.getTotalCount());
        for (Folder folder : foldersResults.getFolders()) {
//        	folder.getId().getFolderName() 这一个api并不是获取文件夹名称,因为id和folerName是互斥的
        	System.out.println("文件夹名称：" + folder.getDisplayName());
            FindItemsResults<Item> findItemsResults = folder.findItems(view);
            for (Item item : findItemsResults.getItems()) {
                EmailMessage message = EmailMessage.bind(service, item.getId());
                System.out.println("发送人->" + message.getSender());
                System.out.println("标题--->" + message.getSubject());
                System.out.println("邮件ID->" + message.getId());
            }

        }
