I got this response from MS: "I have checked that message with my Outlook 2016 in my lab, it doesn't show correctly either. In this situation, I guess the Outlook client doesn't support that HTML format based email. However, from your description, it worked before, so we need to confirm if that email is reformatted by the Exchange Online server as you mentioned the OWA also can't show it correctly. Thanks for your patience."
Which implies that they are not going to fix it. The problem started occurring for us on November 2, 2018 following a Microsoft Office/Outlook update. The system generating the emails (Nunit) has not changed in 5+ years.Rob Kraft supported this idea ·
