Connection problem with MS Exchange Server

[free_soul424]

Hi, I am trying to connect with Microsoft Exchange Server using the following code

static void Main(string[] args)
{ {

System.Net.ServicePointManager.ServerCertificateValidationCallback =delegate(Object obj, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors)
{
return true;
};

ExchangeServiceBinding objExchangeServiceBinding = new ExchangeServiceBinding();
objExchangeServiceBinding.Credentials = new System.Net.NetworkCredential("user", "pass", "domain.com");
//objExchangeServiceBinding.AllowAutoRedirect = true;
objExchangeServiceBinding.UseDefaultCredentials = true;
objExchangeServiceBinding.Url = "https://10.11.1.250/ews/Exchange.asmx";

        FindItemType request = new FindItemType();
        request.ItemShape = new ItemResponseShapeType();
        request.ItemShape.BaseShape = DefaultShapeNamesType.Default;
        request.Traversal = ItemQueryTraversalType.Shallow;
        request.ParentFolderIds = new BaseFolderIdType\[1\];
  DistinguishedFolderIdType inbox = new    DistinguishedFolderIdType();
        inbox.Id = DistinguishedFolderIdNameType.inbox;
        request.ParentFolderIds\[0\] = inbox;

ServerVersionInfo objServerVersionInfo = objExchangeServiceBinding.ServerVersionInfoValue;
}

But I get the following error “The request failed with HTTP status 401: Unauthorized.” Can anyone please tell me what the problem is? I will be thankful to you regards,

Please check your Network credential.if possible then login to OWA from this credential for varification.

Thanks for your reply, I can login to OWA using the same username, password and domain, but it creates problem when I try it through code as I mentioned. :(
