The only caveat is that it only supports Microsoft accounts. You cannot use (at this moment) other services, such as Gmail, Yahoo, Apple’s iCloud, or other services using IMAP. One Outlook (or simply Outlook) is a desktop application that looks identical to the web version but with some new features. For example, this email client includes a single view for email, calendar, and tasks. While the new experience offers a familiar interface with new capabilities, some essential features are still missing. For instance, Outlook does not support offline mode, and you cannot add multiple accounts. However, these features are under development, and other features like Outlook data (.pst) and Folder reordering are part of the roadmap. The idea with the new Outlook app is to replace the legacy Mail and Calendar apps that come built-in to Windows 11, but since it’s still beta and many features are still missing, it’ll take a long time for Microsoft to replace it. If you want to try the app, you can download the latest preview of Outlook from the Microsoft servers. Once you download the “.exe” file, launch it to complete the installation, and sign in with your Microsoft account. All content on this site is provided with no warranties, express or implied.
