How do I switch to Classic outlook from New Outlook

For Windows (Outlook Desktop App) Open the New Outlook. Click the toggle switch at the top right corner that says “New Outlook” to turn it OFF. A confirmation prompt will appear – confirm the switch back to Classic Outlook. Outlook will restart, and you’ll be back in the Classic Outlook version.
