基于WebDAV通过outlook 发送 Email

 以下是一个通用的方法,如果你知道你的Exchange Server (仅限2003和2007版本的Server，往后的Server版本不再支持WebDAV协议，对于更高版本的Exchange Server微软建议调用EWS来发邮件，目前Exchange Server 2007 和 Exchange Server 2010都支持EWS) 那么你就可以调用这个方法来发送Email了,成功发送后在你的outlook的Sent Items中会有记录的.

下例中几个参数的说明：

strSenderAlias，这个参数一般情况下就是你邮箱账号@前面的那段字符串。

strServer，这个参数是你的outlook server 地址，这个可以从outlook客户端菜单栏中有个“Accounts”，进去后选中Microsoft Exchange Server选项，然后点击编辑，就可看到。

 你需要添加如下的引用:

 

using System;

using System.IO;

using System.Net;

using System.Windows.Forms;
