目前我在尝试使用EWS时遇到问题，最初的要求是连接到特定用户的邮件，然后搜索特定文件夹，搜索邮件然后将附件下载到特定文件夹到本地机器，以便稍后它可以由集成服务处理，我不想使用 EWS 托管 API，因为我不想在迁移到生产服务器时安装任何东西，现在我的想法是开发一个 WCF通过 .asmx uri 连接到 EWS 服务并且能够满足我的要求的服务，现在我可以连接到公司的 EWS，但我有一些疑问：
根据微软的说法：http: //msdn.microsoft.com/en-us/library/exchange/bb408524 (v=exchg.150).aspx他们说你必须为你的项目添加一个 Web 服务引用，尽管它只提到了 VS 2005 和 VS 2008（我正在使用 VS 2012），它应该自动创建 ExchangeServiceBinding 类，它为您提供模拟帐户所需的一切，我的第一个问题是：为什么我没有看到这个类添加到我的项目？我应该期望这是因为我使用的是 VS 2012 吗？
好的，无论如何我可以使用getPasswordExpirationTime之类的方法，但是当我使用FindFolder方法时，我收到错误：“该帐户无权模拟请求的用户。”，这是我的方法：
using (ExchangeServicePortTypeClient exchangeServicePortTypeClient = new ExchangeServicePortTypeClient())
{
exchangeServicePortTypeClient.ChannelFactory.Endpoint.Address = new EndpointAddress("https://email.kraft.com/EWS/Exchange.asmx");
FindFolderResponseType findFolderResponseType = null;
exchangeServicePortTypeClient.FindFolder(
new ExchangeImpersonationType
{
ConnectingSID = new ConnectingSIDType
{
Item = @"gilberto.gutierrez@mdlz.com",
ItemElementName = ItemChoiceType1.PrimarySmtpAddress
}
},
null,
new RequestServerVersion { Version = ExchangeVersionType.Exchange2010_SP2 },
null,
new FindFolderType
{
FolderShape = new FolderResponseShapeType
{
BaseShape =
DefaultShapeNamesType.Default
}
}, out findFolderResponseType);
}
我试图通过这个设置凭据：
exchangeServicePortTypeClient.ClientCredentials.Windows.ClientCredential.UserName
exchangeServicePortTypeClient.ClientCredentials.Windows.ClientCredential.Password
exchangeServicePortTypeClient.ClientCredentials.Windows.ClientCredential.Domain
exchangeServicePortTypeClient.ChannelFactory.Credentials.Windows.ClientCredential.UserName
exchangeServicePortTypeClient.ChannelFactory.Credentials.Windows.ClientCredential.Password
exchangeServicePortTypeClient.ChannelFactory.Credentials.Windows.ClientCredential.Domain
没有运气:(。
顺便说一句，这是我的 wcf 配置文件。

如果我删除部分客户端凭据类型“Windows”，则在尝试运行服务时异常是：
HTTP 请求未经客户端身份验证方案“匿名”授权。从服务器收到的身份验证标头是“协商，NTLM”。
你们能帮帮我吗？
谢谢指教。
