Java Exchange 400上载会议时出错

我正在尝试使用Android中的exchange 2010构建一个book your meeting应用程序。 我正在使用activesync来熟悉自己。 到目前为止，我已设法使ResolveRecipients、SendMail和FolderSync命令正常工作。但是当我尝试的时候 要上传会议请求，我收到一个400错误请求。我正在使用 作为参考

我的xml

有没有我遗漏的标题？xml是否有任何错误？如果有人能提供一些线索，我将不胜感激。

我在标题中使用的是activesync版本12.1。

xml看起来不错。确保正确地将xml转换为wbxml。若要仔细检查，请尝试转换回xml并查看是否返回原始字符串。

从未使用过此选项，但日历中的双斜杠：xml中的时区将是我查看的位置。这是我同步日历文件夹时从服务器获得的时区值。即使我删除了时区字段，我仍然会得到相同的错误：(

private HttpPost createHttpPost(String uri, String requestXML,
            boolean includePolicyKey) throws Exception {

        // Set the common headers
        HttpPost httpPost = new HttpPost(uri);
        httpPost.setHeader("User-Agent", "Android");
        httpPost.setHeader("Accept", "*/*");
        httpPost.setHeader("Content-Type", "application/vnd.ms-sync.wbxml");
        //httpPost.setHeader("Content-Type", "message/rfc822");//message/rfc822



        // If we are connecting to Exchange 2010 or above
        // Lets tell the Exchange server that we are a 12.1 client
        // This is so we don't have to support sending of additional
        // information in the provision method
        if(getActiveSyncVersionFloat() >= 14.0)
            httpPost.setHeader("MS-ASProtocolVersion", "12.1");
        // Else set the version to the highest version returned by the
        // Exchange server
        else
            httpPost.setHeader("MS-ASProtocolVersion", getActiveSyncVersion());


        //Log.d(TAG, mActiveSyncVersion);
        httpPost.setHeader("Accept-Language", "en-us");
        httpPost.setHeader("Authorization", mAuthString);

        // Include policy key if required
        if (includePolicyKey)
            httpPost.setHeader("X-MS-PolicyKey", mPolicyKey);

        // Add the XML to the request
        if (requestXML != null) {
            //Log.d(TAG, requestXML);
            // Set the body
            // Convert the XML to WBXML
            ByteArrayInputStream xmlParseInputStream = new ByteArrayInputStream(
                    requestXML.toString().getBytes());

            java.io.ByteArrayOutputStream output = new java.io.ByteArrayOutputStream();
            wbxml.convertXmlToWbxml(xmlParseInputStream, output);
            byte[] bytes = output.toByteArray();

            ByteArrayEntity myEntity = new ByteArrayEntity(bytes);
            myEntity.setContentType("application/vnd.ms-sync.wbxml");
            httpPost.setEntity(myEntity);
        }
        return httpPost;
    }
