The render engine of Out look for Windows

Question

I've encountered some issues when receiving email(the content is written by html and css) by Outlook for Windows. All content are renders well on Web/Mac Outlook except for Windows, some fonts are stripped and some strange space occurs.

Web/Mac: all fonts and layout space work fine

Windows: fonts changed and space gets larger

here is the key html code:

                                <ul style="margin: 0; padding-left: 1.5em;font-family: 'Noto Sans JP', Tahoma, sans-serif;">
                                  <li>積立金額*</li>
                                  <li>解約返戻金*</li>
                                  <li>年金開始日</li>
                                </ul>

May I know who can clarify the render engine of "Outlook for Windows", is there any difference between it from common browser's kernel？

Btw, I found some related article said that "Outlook 2007" uses Microsoft Word to render html content. Is it true and still running on "Outlook for Windows"?
