.NET中使用Exchange 2007 Webservice来读取邮件

来源：互联网发布：js 判断list包含编辑：程序博客网时间：2024/06/05 02:38

很久没有更新过博客了，这几个月比较忙，人也比较懒散，今天已经是八月份，新的一个月希望要换一个状态。今天要写的文章是我四月份写的一个功能，一直拖到现在才发表。在企业内部我们一般都是使用微软的Exchange服务器来进行邮件的存储及发送，我们一般在客户端用outlook来收发邮件。工作中遇到了一个需求，需要写一个程序来抓取邮件服务器的邮件，并将抓取下来的邮件存储到数据库中。之前已经发表过一篇文章，是利用Jmail组件来抓取，可以抓取我们常用的一些邮箱的邮件，比如说163，gmail等，但是不能抓取exchange服务器中的邮件，所以需要重新写，最后决定使用Exchange 2007 中提供的webservice来抓取邮件。网络上这方面的资料很少，所以大部分的参考是来自MSDN：

http://msdn.microsoft.com/en-us/library/exchangewebservices(EXCHG.80).aspx

2007版的Exchange服务器提供了webservice，我们可以方便的在.NET程序中添加该引用，然后就可以方便的实现邮件的抓取，发送，删除等功能。我测试是在控制台程序中使用该webservice，步骤如下：

1 新建一个站点，然后添加exchange webservice 的引用，输入邮件服务器的OWA地址：http://yourmailserver/EWS/Services.wsdl,如果是在公司的内部域中，添加的过程中要求输入你的域帐号和密码。

2 添加成功以后再项目中导入该命名空间以其他必须的命名空间;

3 下面就是具体的代码，具体的请看注释：

发送邮件：

public static void CreateEmail(string userName, string passWord, string domain, string url, string mailFrom, string mailTo)
