PROPFIND - The remote server returned an error: (501) Not Implemented. Exchange Server 2003

Can you show the code you are using (relevant parts)

           HttpWebRequest Request;
            WebResponse Response;

            strFolderURI = "http://exch1/exchange/PFAdminTest/Inbox/";
            //strFolderURI = "http://exch1/public/Test%20Fileplan/Another";

            try
            {
                string strQuery = "<?xml version='1.0' ?>"
                   + "<f:propfind xmlns:f='DAV:'>"
                   + "<f:prop xmlns:m='http://schemas.microsoft.com/exchange/security/'>"
                   + "<m:descriptor/>"
                   + "</f:prop>"
                   + "</f:propfind>";

                // Create the HttpWebRequest object.
                Request = (HttpWebRequest)HttpWebRequest.Create(strFolderURI);

                // Add the network mCredentials to the request.
                Request.Credentials = mCredentials;
                Request.PreAuthenticate = true;

                // Specify the method.
                Request.Method = "PROPFIND";

                // Encode the body using UTF-8.
                byte[] bytes = Encoding.UTF8.GetBytes(strQuery);

                // Set the content header length.  This must be
                // done before writing data to the request stream.
                //request.ContentLength = bytes.Length;

                // Get a reference to the request stream.
                Stream RequestStream = Request.GetRequestStream();

                // Write the SQL query to the request stream.
                RequestStream.Write(bytes, 0, bytes.Length);
               
                // Close the Stream object to release the connection
                // for further use.
                RequestStream.Close();

                // Set the content type header.
                Request.ContentType = CONTENT_TYPE_XML;

                Response = (HttpWebResponse)Request.GetResponse();

                Stream ResponseStream = Response.GetResponseStream();

Used BPROPFIND instead. This seems to work fine.

wow, wonder why it didn't work the first time. was working up more code to test this out.

Request to close this one.

Please check the firewall
