Fail to get eml item - Githubissues

Hi all,

When I request a eml at office 365 mail via EWS mgr API which has size bigger than 20MB

curl -X POST  -
v https://outlook.office365.com/EWS/Exchange.asmx  
-H 'authorization: Bearer [my token]'   
-H 'cache-control: no-cache'   
-H 'content-type: text/xml; charset=utf-8'  
-d '
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types"

  </soap:Header>
  <soap:Body>

      <m:ItemShape>
        <t:BaseShape>IdOnly</t:BaseShape>
        <t:IncludeMimeContent>true</t:IncludeMimeContent>
      </m:ItemShape>
      <m:ItemIds>
        <t:ItemId Id="AAMkADVmMzE2MjY0LTZkOGYtNGI4MS1iNWMxLTljYzg3MWY5MW
                QxMQBGAAAAAABZMfR36TVMQ6yunaqZPvVRBwAF9fKWjhbKTIB6d
                NkgJcvkAACMMEXVAAAF9fKWjhbKTIB6dNkgJcvkAACQktc5AAA="/>
      </m:ItemIds>
    </m:GetItem>
  </soap:Body>
</soap:Envelope>
' 
-o out

Sometimes it only returns part response, ends in middle of base64 encoded string in tag MimeContent

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  blahblah...
<m:Items>
<t:Message>
<t:MimeContent CharacterSet="UTF-8">UmVjZWl2ZWQ6IGZyb20gS0wxUFIwN _[EOF]_

And the response header: http status code 200
