Exchange Web Service is Supported For Exchange2007_SP3

我正在尝试使用EWS获取收件箱文件夹信息。

 ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);**//Here Exchange2007_SP3 version not coming.Only(Exchange2007_SP1,Exchange2010,Exchange2010_SP1,Exchange2010_SP2) are available**
 service.Credentials = new WebCredentials(UserName, Password, DomainName);
 service.Url = new Uri("HTTPS://" + ServerName + "/EWS/Exchange.asmx");
 Folder rootfolder = Folder.Bind(service, WellKnownFolderName.Inbox);**//Error Arises**
 foreach (Folder folder in rootfolder.FindFolders(new FolderView(int.MaxValue)))
 {
 }

I am Getting Error:客户端访问服务器版本与访问的资源的邮箱服务器版本不匹配。使用AutoDiscover和被访问资源的地址来确定用来访问指定资源的正确URL。

 If i use autodiscover service , For that to error arises.
 service.AutodiscoverUrl("adminuser@Domain.com",RedirectionUrlValidationCallback);

I am Getting Error:无法找到自动发现服务。
