Hi @dorbi ,
According to my test, in the New outlook interface, these shortcuts may have been changed.
The New outlook seems to use the shortcut keys for the web, when I change the setting to outlook for web, it works, but the shortcut keys have changed, you can press Shift+? to view the available shortcut keys.
You can refer to the steps:
1.Click Settings > View all the Outlook settings:
2.Click General > Accessibility > check on Outlook for Web
3.Press Shift+? you can view the available shortcut keys.
The new Outlook is not yet complete, and some options may not be available or work as expected. You can switch back to the classic Outlook at any time by clicking the toggle button in the top right corner of the window.
