Cannot send email with EWS Java API

Question

I am using EWS to send emails on Exchange 2010 as follows:

ExchangeService service = new ExchangeService();
ExchangeCredentials credentials = new WebCredentials(email, password);
service.setCredentials(credentials);
service.setUrl(new java.net.URI("https://" + host
    + "/EWS/Exchange.asmx"));
service.setTraceEnabled(true);

EmailMessage msg = new EmailMessage(service);
msg.setSubject("Hello world!");
msg.setBody(MessageBody.getMessageBodyFromText("Sent using the EWS Managed API."));
msg.getToRecipients().add("email");
msg.send();

The message is not delivered to the inbox and I don't know what is the problem. After I enabled tracing, I get the following:

<Trace Tag="EwsRequestHttpHeaders" Tid="1" Time="2012-10-14 11:13:46Z">
    POST /EWS/Exchange.asmx HTTP/1.1

The exchange server is responding that all is ok:

<?xml version="1.0" encoding="utf-8"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Header>
    <h:ServerVersionInfo MajorVersion="14" MinorVersion="1" MajorBuildNumber="218" MinorBuildNumber="14" Version="Exchange2010_SP1" xmlns:h="http://schemas.microsoft.com/exchange/services/2006/types" xmlns="http://schemas.microsoft.com/exchange/services/2006/types" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"/>
  </s:Header>
  <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <m:CreateItemResponse xmlns:m="http://schemas.microsoft.com/exchange/services/2006/messages" xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types">
      <m:ResponseMessages>
        <m:CreateItemResponseMessage ResponseClass="Success">
          <m:ResponseCode>NoError</m:ResponseCode>
          <m:Items/>
        </m:CreateItemResponseMessage>
      </m:ResponseMessages>
    </m:CreateItemResponse>
  </s:Body>
</s:Envelope>

You should check on the Exchange side, or ask your Exchange server admin about what's going on (for example some spam filtering or whatever else), because from a code perspective and SOAP Request/Response point of view, there's nothing wrong.

can you please tell me where to check the spam filtering in the exchange server ? — Mahmoud Saleh, Oct 18 '12 at 08:11

          <t:Message>
            <t:Subject>Hello world!</t:Subject>
            <t:Body BodyType="HTML">Sent using the EWS Managed API.</t:Body>
            <t:ToRecipients>
              <t:Mailbox>
                <t:EmailAddress>adamb@fabrikam.com</t:EmailAddress>
              </t:Mailbox>
            </t:ToRecipients>
          </t:Message>

Please check the inbox of adamb@fabrikam.com or talk to an Exchange administrator to look at the mail queues, filters, many other things etc. that might stop the email from coming. Nothing wrong with your posted code.
