FetchXML to get email CC email addresses

Hi, can anyone help me with a fetchXML query? I am getting a list of email message fields. the purpose is to display the actual to / from / cc / bcc email addresses in a form via a webresource.

I have the fetch XML working, but get activityparty: and a guid for cc and bcc.

my simplified (I've removed a couple of conditions)  fetchXML so far is:

<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false' >
  <entity name='email' >
    <attribute name='sender' />
    <attribute name='torecipients' />
    <attribute name='subject' />
    <attribute name='senton' />
    <attribute name='cc' />

  </entity>
</fetch>
