Office 2016 not show a preview for arabic fonts in fonts drop-down-list like it was in all previous products Tuesday, January 2, 2018 12:01 PM Reply. I just bought Office 2016 and it does NOT include all the fonts in the 2013. And my download, installed in August, does not include at least half of the fonts the person helpfully transcribed in an answer above.
Helvetica Neue is a commercial font from Linotype. You cannot legally obtain it for free. It's available from reputable online vendors such as and for $49 per style; you might need only one, such as Helvetical Neue 55 Roman. Has suggestions for free alternatives. However you obtain any font, if you download it as a zip file, you would right-click it and choose to extract the ttf file from it; then right-click the ttf file and choose Install.
