I understand that it’s one of Microsoft’s goals to make the new Monarch client feel as native to the OS as possible while remaining universal across platforms by basing the app on the Outlook website. The report from Windows Central highlights that the new web-based Outlook will have “a much smaller footprint and be accessible to all users whether they’re free Outlook consumers or commercial business customers.”Įven though it will be a universal web app, it looks like Microsoft is planning to include native integrations for Mac and Windows like sharing, offline storage, and notifications. The effort is codenamed “Project Monarch” and will offer the same UI and design no matter if you’re accessing it via Mac, Windows, or the web. Reported by Windows Central, the move by Microsoft is to simplify Outlook so it’s just one product that works across all devices. Notably, the biggest part of that includes a controversial shift from dedicated Mac and Windows apps to a web-based app that’s platform agnostic. As Microsoft looks toward the future, “One Outlook” is the vision for how its mail and calendar app will evolve.
