I am testing the Microsoft Exchange Web Service Java API (version 1.2) to read mails from a server. Here is my code:
String url = "https://my-server/EWS/exchange.asmx";
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
service.setTraceEnabled(true);
service.setCredentials(new WebCredentials("user", "password"));
service.setUrl(url.toURI());
Mailbox mailbox = new Mailbox("[email protected]");
FolderId folder = new FolderId(WellKnownFolderName.Inbox, mailbox);
ItemView view = new ItemView(10);
view.getOrderBy().add(ItemSchema.DateTimeReceived, SortDirection.Descending);
FindItemsResults<Item> items = service.findItems(folder, view);
Unfortunately, this code throws the following error:
Exception in thread "main" microsoft.exchange.webservices.data.EWSHttpException: Connection not established
at microsoft.exchange.webservices.data.HttpClientWebRequest.throwIfConnIsNull(Unknown Source)
at microsoft.exchange.webservices.data.HttpClientWebRequest.getResponseCode(Unknown Source)

I'm not able to understand what is wrong with the current code. Do you have any clue, or at least some tests to try?
Note that the web-service (https//my-server/exchange.asmx) is accessible to my Java code.
Not sure if it can help, but I've found that in the traces displayed by the logs:
<Trace Tag="EwsResponse" Tid="1" Time="2013-01-28 10:47:03Z">
<html><head><title>Error</title></head><body>The function requested is not supported
</body></html>
</Trace>
EDIT
I've made another test. This time, I use the defaults credentials - so my own email account - using service.setUseDefaultCredentials(true); instead of setting the WebCredentials object. The connection is still not established, but I get another error (I've took only the interesting part of the trace log):
<h1>You are not authorized to view this page</h1>
You do not have permission to view this directory or page using the credentials that you supplied because your Web browser is sending a WWW-Authenticate header field that the Web server is not configured to accept.
(...)
<h2>HTTP Error 401.2 - Unauthorized: Access is denied due to server configuration.<br>Internet Information Services (IIS)</h2>
Of course, I can't access nor change anything on the Exchange server side. Is there a way to make the authentication successful?
