Deploying new features to a massive 100-million plus user community takes a lot of planning and careful management. Outlook Mobile caters for both consumer and commercial users, and different methods are used to deliver new features to the two groups. Sometimes this means that different users in the same tenant can’t access a new feature even if they have the right software.
Outlook mobile users now have shared mailbox support in both iOS and Android platforms. The work to upgrade the backend service is also progressing and is past 50% rollout. And dark mode is coming too. It’s available in beta today to Testflight users (only for iOS), and it’s also been enabled for some users who run the latest version of the clients.
The new version of OWA is maturing and new features are turning up on a weekly basis. You can now schedule a Teams meeting from OWA and the prospect of joyful animations hang in the air. But only for Office 365 users as there’s no sign that the new OWA will come to Exchange on-premises servers.
