I am using the below endpoint to read mail messages from a given mail folder but I see the message does not contain header information.
Endpoint- https://graph.microsoft.com/v1.0/me/mailFolders/{folderid}messages/?$orderby=sentDateTime

When using java mail API to read the same messages I could able to retrieve the headers information as-
#java_mail
javax.mail.Message message= some object;
Enumeration headers = message.getAllHeaders();
There is no clarity in documentation regarding this.
I see some places to use below in Graph API
com.microsoft.graph.models.Message message = some msg obj;
List headers = message.internetMessageHeaders;
but there is no internetMessageHeaders value in response.
It is strange for me that when reading via javax.mail.Message i can retrieve headers but not via MS Graph API com.microsoft.graph.models.Message.
Is there any way to achieve this using an MS graph API?
