Outlook for Windows (also referred to as New Outlook) is an email client developed by Microsoft. It is a replacement of the preloaded Windows Mail and Calendar apps on Windows 10 and 11, and will ship as default with Windows 11 from late 2024 onwards.[2][3]
The new Outlook was outlined under Microsoft's 'One Outlook' plan, with testing starting in 2022.[4] In September 2023, Microsoft started transitioning users of the previous apps to the new Outlook.[5] It was released on the Microsoft Store that month, although it remains in preview status.[6]
The free version includes advertising, and does not currently enable all IMAP accounts to be set up. It does not support iCloud aliases. It does not work offline.[10]
