I've been looking at embedding html 5 video / audio in email. I’ve got it working great on iOS10 and Apple Mail. However, I can’t get the play button to work on Outlook for mac. I can only play/pause by right clicking.

My code looks like this:

        <audio controls>
            <source src="audio.mp3" type="audio/mpeg">
        <video width="320" height="176" controls>
            <source src="video.mp4" type="video/mp4">
            <source src="video.ogg" type="video/ogg">

Does anyone know a workaround or a way to target outlook for mac?
