Exchange2010 Ews 调用的时候需要注意到事项（模拟用户权限）

第一：在调用的时候需要（2010 采用的是SSL加密的形式，所以我们调用的时候需要加上如下的代码，）

 

 ExchangeVersion RequestedServerVersion = config.ExchangeVersion == "2007" ? ExchangeVersion.Exchange2007_SP1 : ExchangeVersion.Exchange2010;
            System.Net.ServicePointManager.CertificatePolicy = new TrustAllCertificatePolicy();
            service = new ExchangeService(RequestedServerVersion)
                          {
                              Url = new Uri(config.EWSServiceUrl),
                              Credentials = new NetworkCredential(config.ExchangeAdministrator,
                                                                  config.ExchangeAdministratorPassword,
                                                                  config.Domain),
                            


                          };

 

    public class TrustAllCertificatePolicy : System.Net.ICertificatePolicy
    {
        public TrustAllCertificatePolicy()
        { }

        public bool CheckValidationResult(ServicePoint sp,
            System.Security.Cryptography.X509Certificates.X509Certificate cert,
            WebRequest req, int problem)
        {
            return true;
        }
    }

 

关键是如下句：

 

System.Net.ServicePointManager.CertificatePolicy = new TrustAllCertificatePolicy();

 
 

第二：打开Exchange 2010 服务器在命令行中输入

New-ManagementRoleAssignment -Name:impersonationAssignmentName -Role:ApplicationImpersonation -User:serviceAccount

serviceAccount：就是我们要模拟其他人的账户
