Hi, all.

In work-time with Exchange Server 2003 with WebDAV we found next strange bug:

sometimes, this code (uses for get a localized name of the Inbox folder) launched from the same with Exchange domain

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

strBody = "<?xml version='1.0' encoding='utf-8'?>";

strBody += "<a:propfind xmlns:a='DAV:' xmlns:h='urn:schemas:httpmail:'>";

strBody += "<a:prop><h:inbox/></a:prop></a:propfind>";

Request = (System.Net.HttpWebRequest)HttpWebRequest.Create(mailboxRoot);

Request.Credentials = new NetworkCredential(LinkageSystemUserName, LinkageSystemUserPass, ExchangeServerDomain);

Request.Method = "PROPFIND";

Request.PreAuthenticate = true;

Request.ServicePoint.Expect100Continue = false;

Request.ServicePoint.UseNagleAlgorithm = false;

bytes = System.Text.Encoding.UTF8.GetBytes(strBody);

Request.ContentLength = bytes.Length;

RequestStream = Request.GetRequestStream();

RequestStream.Write(bytes, 0, bytes.Length);

RequestStream.Close();

Request.ContentType = "text/xml";

Request.Headers.Add("Depth", "0");

Response = (HttpWebResponse)Request.GetResponse();

Stream ReceiveStream = Response.GetResponseStream();

System.Text.Encoding encode = System.Text.Encoding.GetEncoding("utf-8");

StreamReader sr = new StreamReader(ReceiveStream, encode);

string XmlData = sr.ReadToEnd();

ReceiveStream.Close();

sr.Close();

Response.Close();

works only one time, on all next times server returns (400) Bad request (this continue ~10 minutes, after this it again works one time).

If we launch this code from another domain all working fine.
