In June, we announced new APIs in the beta endpoint of the Outlook REST API. Today we’re excited to announce that those APIs have been added to the Microsoft Graph, along with some other highly-requested APIs. All of these new APIs are added to the beta version of the Microsoft Graph API.

Try these new APIs out today, either in your code or in the Graph Explorer. Leave feedback on the new APIs on UserVoice.

Message headers

The Microsoft Graph API has added the RFC5322 message headers to the message resource. The headers are available in the internetMessageHeaders property, which is a collection of internetMessageHeader resources. The internetMessageHeaders property is not in the default property set for messages, so you must request it explicitly using the $select query parameter.
