As you may be aware a new Outlook Web Access (aka Outlook on the Web) user experience has been in preview for quite some time now; you were able to switch on and off this experience using the toggle ‘The new Outlook’ available at the top right side:
Well, this new experience is now becoming the default (and only) user experience starting July 22nd with a complete rollout estimated by end of September.
Start preparing your users about this UI change. The new experience applies to Mail, Calendar and People.
The Tasks section is not (yet) affected by this change and the toggle will remain available to switch between ‘old’ and ‘new’ UI until further notice.
