Microsoft Unveils New Outlook for Windows: A Preview Overview

Microsoft plans to replace the classic Outlook with a new, unified app for email and calendar. It's currently in preview for organizations


has announced its comprehensive plan to migrate organizations to the new Outlook for Windows email and calendar application. Currently in preview for commercial customers, the updated Outlook shares its codebase with Outlook on the Web but does not yet match the classic version in features. With this move towards a unified codebase known as One Outlook, Microsoft is signaling a significant shift in its approach to software development, aiming for a more integrated and consistent user experience across platforms.

Detailed Rollout Plans

According to a detailed timeline shared by Microsoft, while exact dates were not provided, the company hinted at a two-year rollout phase that began in September. Contrary to previous statements claiming the new Outlook for had already launched for personal and organizational use, it now appears the application is still in a preview phase, albeit without the explicit ‘preview' labeling. This strategic preview phase allows organizations to explore the new interface with a simple toggle option, easing the transition between the old and new versions.

As feedback is gathered and more features are added, Microsoft will transition the new Outlook for Windows into general availability, indicating that all relevant customers will have access to full support services. Subsequently, the application will enter an “opt-out” phase where the new version becomes the default option, yet allowing users to revert to the classic version temporarily. The final “cutover” phase will mark the complete replacement of the classic client, with no option to revert, reflecting Microsoft's long-term vision for its email and calendar services.

User Feedback and Future Support

User feedback on online forums has highlighted concerns over missing features in the new Outlook that were available in the classic version. Microsoft acknowledges these concerns and is working toward achieving feature parity. For users hesitant to make the switch, Microsoft assures that the classic Outlook will remain supported for perpetual license holders until at least 2029, offering a generous adjustment period.

The new Outlook for Windows marks a significant step in Microsoft's ongoing efforts to streamline its software offerings, promising a more integrated and user-friendly experience. As the company moves closer to general availability, both organizations and individual users are keen to see how these changes will enhance their daily productivity and communication workflows.
