Last week, Microsoft also announced that it was making Outlook for Mac free to use on macOS. However, if you really like the ability to create unified inboxes in the UWP Mail app, the new web-based Outlook doesn’t have that feature yet. These two apps haven’t been updated in ages, so this new Outlook for Windows should be quite an upgrade. The new web-based Outlook for Windows is set to replace the UWP-based Mail and Calendar apps on Windows 10 and Windows 11 at some point. While the UI is nothing to complain about, Outlook power users who require specific add-ins will likely stick with what Microsoft now calls the “classic Outlook for Windows.” Microsoft’s new Outlook app for Windows looks a lot like Outlook on the web, though it supports multiple accounts (again, only personal MSA accounts or work or school accounts at the moment).

IT pros will also be able to hide the toggle by using a registry key. We will give notice before any required changes occur, after the preview has received sufficient usage and feedback,” Microsoft explained on the Microsoft 365 Admin Center.

“The experience is an option to try, and nothing will change without end users taking action. The toggle to try the new web-based Outlook app will only appear for Outlook users using accounts by the new app, which are currently quite limited: The new Outlook client only supports Microsoft Exchange Online and personal Microsoft accounts, though Microsoft is planning to add support for more accounts “within the next month.” The new app is currently available via a toggle on the Office Insiders Beta and Preview channels, but the same toggle will become available on the Current Channel in early April. Microsoft is getting ready to make its new web-based Outlook for Windows app available for all users.
