The theme applies coordinated visual styling, layout, typography, icons, and interaction changes to make New Outlook feel more familiar to users transitioning from Classic Outlook. It won't override admin configurations or auto-migrate users, and can be toggled on or off anytime from Settings > General > Appearance. It will be off by default for most users but on by default for some users actively moving from Classic to New Outlook. This follows Microsoft's February decision to push the Classic Outlook opt-out deadline for businesses from April 2026 to March 2027, and a July announcement to retire OWA Light in a future Exchange Server update. ## Full article daily.dev links to this article rather than hosting it.
