With usage growing daily in our preview experience, we are rolling out Outlook for Mac to Preview Channel as the default experience for any user who has never tried the new experience. The default-on Outlook toggle provides access to enhanced performance and user experience across Mail, Calendar, People, and Search.
We announced the toggle in July 2020 (MC219576).
