Sharepoint2013 获取用户邮箱信息

有的时候，在作Sharepoint开发的时候咱们须要获取用户的邮件信息，一般都是经过调用EWS API来实现。

如下是实现的核心代码：

第一步须要在Exchange服务上受权一个帐户有模拟其余用户的权限，在Exhcange服务上打开Exchange powershell命名窗口，输入下面命名

New-ManagementRoleAssignment -Name:impersonationAssignmentName -Role:ApplicationImpersonation -User:须要受权的帐号

 

//模拟用户名，密码，域
string ImpersonatedUser="test";
string ImpersonatedPwd="test";
string domain="test";
//目标用户邮箱地址
string emailserverAddress="user1@test.com.cn";
//ExchangeService版本为2013
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013);
service.Credentials = new NetworkCredential(ImpersonatedUser, ImpersonatedPwd, domain);
//打开目标用户的邮箱地址
service.Url = new Uri(emailserverAddress);
//对目标用户进行模拟
service.ImpersonatedUserId = new Microsoft.Exchange.WebServices.Data.ImpersonatedUserId(Microsoft.Exchange.WebServices.Data.ConnectingIdType.SmtpAddress, UserMailAddress);
//只读取目标用户未读的信息
SearchFilter sf = new SearchFilter.IsEqualTo(EmailMessageSchema.IsRead, false);
//只读取前10条信息
ItemView view = new ItemView(int.Parse(top));
FindItemsResults<Item> findMailResults = service.FindItems(WellKnownFolderName.Inbox, sf, view);
if (findMailResults.Count() > 0)
{
foreach (Item m in findMailResults)
{
    EmailEntity em = new EmailEntity();
    Microsoft.Exchange.WebServices.Data.EmailMessage e = Microsoft.Exchange.WebServices.Data.EmailMessage.Bind(service, m.Id);
    em.ID = e.Id.ToString();
    em.Subject = e.Subject;
    lists.Add(em);
}
}
