We are excited to announce the availability of the new Outlook for Mac for our Insider Slow users. The updated and revamped new Outlook is available via a toggle switch on the top right corner of your Outlook main window. The new Outlook for Mac is built on Microsoft sync technology that is fast, reliable, and allows us to bring you the latest and greatest functionality from Microsoft 365. An updated user experience and added features enable you to customize your email, all while keeping things simple and efficient. 


In order to try the new Outlook for Mac, first you will have to join Insider Slow. The default experience will be the current version of Outlook. To navigate to the new experience, simply click the “New Outlook” toggle in the top right corner of the Outlook window. You can switch quickly between the new Outlook for Mac and the current version to compare the differences for yourself and see everything it has to offer.
