When you search on web you will find very easy answers for "How to read emails programmatically"... Al the websites are explaining most of the same like this page. http://omegacoder.com/?p=454

// depends from Exchange server version      
        service.Credentials = new NetworkCredential("MDR", "password", "zzz");
        service.AutodiscoverUrl("mdr@zzz.be");
        object o = service.FindItems(WellKnownFolderName.Inbox, new ItemView(10));
        FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox, new ItemView(10));
        foreach (Item item in findResults.Items)
        {
            Console.WriteLine(item.Subject);
        }

it fails when it executes the autodiscoverURL line. The error says "The Autodiscover service couldn't be located."

So I googled further and found this site from Microsoft https://www.testexchangeconnectivity.com/#&&/wEXAQUBcwUBME93h2+JjI0+MV2gTqcRL0g43z9m Here you can test your mail server.... When I pass the parameters I get the error below....

But I still don't understand what the problem is? Do I need to add a record to DNS ? Can someone help?
