Outlook for Windows (also referred to as New Outlook) is an email client and personal information manager developed by Microsoft. It is a replacement for the preloaded Windows Mail and the contact management Windows People app on Windows 10 and 11[2] and is preinstalled with all versions of Windows 11 since October 2023 (beginning with version 23H2) and Windows 10 since January 2025 (starting with KB5050081).[3]

History

Outlook for Windows 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 remained in preview status for enterprise and education users.[6]

Features

Outlook for Windows is a web app based on the WebView2 runtime,[7][8] and builds on features found in Outlook on the web.[5] It still lacks some features from Microsoft Outlook (which Microsoft refers to as Classic Outlook in this context[9]), such as support for .pst files, which is due to be added at a future date.[10][6]

The free version includes advertising and allows IMAP accounts to be set up.[11] It does not support iCloud aliases, but it is able to work offline.[12][13]

Controversy

Outlook for Windows has attracted controversy surrounding the decision to synchronize emails from non-Microsoft accounts with the Microsoft cloud, rather than downloading the email to local devices as previous Outlook clients have done. Concerns have been raised around the privacy implications of such a system.[14]
