I was looking around and it does seem like the new Outlook lacks this feature at the moment Is there a way to access VBA/Developer in the latest version of - Microsoft Community as this thread seems to confirm. The new Outlook is basically a PWA for the Outlook.com. I flipped the switch to "Try New Outlook" and you can see it is highly nerfed. Luckily you can flip the switch back to the previous version. I sent feedback selecting missing functionality and switched back to the Outlook I had.
