New Outlook for Mac Preview becomes the default experience in the Preview Channel

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).

Note: If your organization does not use Outlook for Mac you can safely disregard this message.

When this will happen

We will begin rolling this out in early June and expect to complete rollout late August.

How this will affect your organization

Users will be switched into the new Outlook for Mac experience upon starting the client. Users can turn the toggle off to switch back to the legacy experience as desired. The feature update uses Microsoft sync technology and the updated experience offers an easily customizable experience that uses Microsoft Services to provide relevant suggestions and insights.
