我的解決方案：

static void Main(string[] args) 
{ 
    ServicePointManager.ServerCertificateValidationCallback = delegate(Object obj, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors) 
    { 
     if (errors == System.Net.Security.SslPolicyErrors.None) 
     { 
      return true; 
     } 

     if ((errors & System.Net.Security.SslPolicyErrors.RemoteCertificateChainErrors) != 0) 
     { 
      if (chain != null && chain.ChainStatus != null) 
      { 
       foreach (System.Security.Cryptography.X509Certificates.X509ChainStatus status in chain.ChainStatus) 
       { 
        if ((certificate.Subject == certificate.Issuer) && 
         (status.Status == System.Security.Cryptography.X509Certificates.X509ChainStatusFlags.UntrustedRoot)) 
        { 
         continue; 
        } 
        else 
        { 
         if (status.Status != System.Security.Cryptography.X509Certificates.X509ChainStatusFlags.NoError) 
         { 

          return false; 
         } 
        } 
       } 
      } 

      return true; 
     } 
     else 
     { 
      return false; 
     } 
    }; 

    ExchangeService _service = new ExchangeService(ExchangeVersion.Exchange2010); 
    _service.Credentials = new WebCredentials("user", "password"); 
    _service.Url = new Uri("https://mail.domain.com/ews/exchange.asmx"); 

    //Contact mailbox 
    ContactsFolder contactsfolder = ContactsFolder.Bind(_service, WellKnownFolderName.Contacts); 

    int numItems = contactsfolder.TotalCount < int.MaxValue ? contactsfolder.TotalCount : int.MaxValue; 

    ItemView view = new ItemView(numItems); 

    view.PropertySet = new PropertySet(BasePropertySet.IdOnly, ContactSchema.DisplayName); 

    FindItemsResults<Item> contactItems = _service.FindItems(WellKnownFolderName.Contacts, view); 

    foreach (Item item in contactItems) 
    { 
     if (item is Contact) 
     { 
      Contact contact = item as Contact; 
      Console.WriteLine(contact.DisplayName); 
     } 
    } 

    Console.ReadLine(); 
}
