Noticed the reply/reply-all/forward options disappeared, when right-clicking on the email (subject/first-line listing column, Outlook-on-the-web). Guessing this was intentional.
These options are still there beside the MORE ACTIONS ellipsis (far right side of screen). I checked the Edge, and Edge Chromium Dev and Chrome browsers.

I still have them and you can customize the actions now: https://outlook.office.com/mail/options/mail/surfaceActions

We are also missing forward/reply/reply-all on right click.
Reply-all/Reply/Forward are not available as Quick Actions is the new Surface Actions/Customized Actions Outlook settings panel either.
