已好几个月没写博客了，由于之前忙于开发基于Sharepoint上的移动OA（AgilePoint）和采用混合移动开发技术开发一个安卓版的企业通讯录APP（数据与lync一致），并于1月初正式上线。马年初二的时候，有个天津的网友加我QQ，说我之前发表博客SharePoint 2013中修改windows 活动目录(AD)域用户密码的WebPart（免费下载），的确对他有帮助，要捐助78元给我，希望我多发表相关的经验总结分享，本人深受鼓舞，并把修改AD域用户密码发他参考学习研究，并在初五合作了另外的Sharepoint 2013开发需求，并通过淘宝支付了定金，能够帮助他人解决问题，得到他人的认可还是蛮开心的。
今天分享一下在1月初完成的KMS与OA的门户整合中其中用到的一种读取Exchange的用户未读邮件数方法，由于KMS是基于Java开发的，并且通过Cas已实现了SSO，需要通过接口把当前登录用户的未读取邮件数显示在KMS中，点击直接进入到OWA页面，如下图：
本文主要通过采用EWS API方式自定义开发一个Web服务，并授权一个账户有模拟其他用户的权限，具体如下：
1.安装Microsoft Exchange Web Services Managed API 2.0，下载地址如下：
http://www.microsoft.com/en-us/download/details.aspx?id=35371
2.0版本支持Exchange Server 2007 Service Pack 1以上，即包括Exchange Server 2010 Service和 Exchange Server 2013 Service。
2.在Exchange服务器中授权一个账户有模拟其他用户的权限，具体如下：
以Exchange 2010 Server为例，比如授权spadmin账号模拟其他用户的权限，打开Exchange 2010服务器在命令行中输入：
New-ManagementRoleAssignment -Name:impersonationAssignmentName -Role:ApplicationImpersonation -User:spadmin
3.利用EWS API开发一个自定义的读取Exchange的用户未读邮件数Web服务，已供其他系统（如KMS）调用，完整的C#代码如下：
