For those finding this message sometime later, pulling your hair out trying to understand why Microsoft didn't make this clear in the documentation, see this post: Can Office 365 REST API send an email with both plain text and HTML body?

I've confirmed this on my end - once the graph API request is made, the Exchange server does, in fact, strip the HTML characters, creates a multipart message (with boundaries) and delivers in the appropriate format.

In my case, I only needed to set the following:

body.contentType = BodyType.HTML;
body.content = myCustomEmailObject.getHtml();

Here's an example of what the raw response (email source) looks like in gmail:

Content-Type: text/plain; charset="us-ascii"
Content-Transfer-Encoding: quoted-printable

This is the content
And this is a new line...

<body>
<b>This is the content</b><br>
And this is a new line...
</body>
</html>
