Using New Outlook on Windows for personal email, calendar, and contact management
My company has the same problem too. I was able to finally find the settings section of the New Outlook (click the three dots next to the account and select Manage Account), but there's no Trust Center. Even if you search the settings for Trust, it says "We couldn't find any results". So, this answer from Microsoft comes from someone who's not even using the new Outlook to solve the problem. Another useless answer.
In another post on where to find the Trust Center in the New Outlook, this was the answer, "the New Outlook is a beta version and it is basically a web-based application and some features are still missing."
Viewing the hyperlink before clicking it is an important step when checking if an email is phish or not. But Microsoft seems to think clicking hyperlinks to see where they take you is safe, and I can't find a solution other than switching back to the Outlook Classic and preventing my company from using the New Outlook.
