Outlook for Windows

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.

The new Outlook was outlined under Microsoft's 'One Outlook' plan, with testing starting in 2022. In September 2023, Microsoft started transitioning users of the previous apps to the new Outlook. It was released on the Microsoft Store that month, although it remains in preview status.

Outlook for Windows is a web app based on the WebView2 runtime, and builds on features found in Outlook on the web. It still has some features from Microsoft Outlook (which Microsoft refers to as Classic Outlook in this context ) missing like .pst files.

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.
