title: How to set the contact title using Exchange Web Services Managed API
body: <p>I'm trying to create a new contact using the EWS API. I can set all the values i needed except the contact title property. I tried the code:</p>
  
  <pre><code>oContact = new Contact(oService);
  oContact.GivenName = "John";
  oContact.Surname = "Doe";
  oContact.Displayname = oContact.Surname;
  
  // set the title property as extended property
  // reference: http://msdn.microsoft.com/en-us/library/gg274394.aspx
  ExtendedPropertyDefinition oTitleProp = new ExtendedPropertyDefinition(
    new Guid("{00062004-0000-0000-C000-000000000046}"),
    0x3A45,
    MapiPropertyType.String);
  oContact.SetExtendedProperty(oTitleProp, "Mr.");
  
  oContact.Save();
  </code></pre>
  
  <p>I'm not getting an error but when i check the title field in outlook 2010, it's empty. I’m using Exchange 2010.</p>
  
  <p>Any ideas what i did wrong?</p>
  
  <p>Kind regards</p>
