Microsoft is set to transition Microsoft 365 Enterprise users from the Classic Outlook app to the New Outlook for Windows starting in April 2026. This strategic move aims to enhance user experience by integrating modern features that align with contemporary workplace needs.
The tech giant has been actively developing the New Outlook, focusing on improving offline usability, an area where Classic Outlook has traditionally excelled. As Microsoft strives to encourage users to adopt its new application, it recognizes the importance of refining the New Outlook to meet user expectations and preferences.
In a recent announcement, Microsoft detailed the timeline for this significant migration, emphasizing that users will have the option to revert back to the Classic Outlook if they choose. The company has made it clear that feedback from users will play a crucial role in shaping the final product. Microsoft stated:
“Starting April 2026, Microsoft 365 for Enterprise users will be switched from Classic Outlook for Windows to New Outlook for Windows, with the option to revert back. This change aims to enhance user experience with modern features.”
This transition is designed to be seamless, requiring no administrative action from organizations. However, users will receive notifications within the application prior to the switch, allowing them to prepare for the change. The rollout will be automatic, but organizations will have the ability to opt out if necessary.
The migration process is structured to provide ample notice—over 12 months—giving organizations sufficient time to adapt. Microsoft’s goal is to familiarize users with the New Outlook, which boasts a host of innovative features, including Copilot functionalities, customizable theming options, and various time-saving tools such as mail pinning and snoozing.
Microsoft has encouraged users to provide feedback on their experiences with the New Outlook. Users can easily share their thoughts through the Feedback option available in the Help ribbon. This input is vital for Microsoft as it seeks to optimize the email and calendar experience for its users.
In addition to the migration details, Microsoft has also outlined specific exceptions where users may not be transitioned to the New Outlook. This information is crucial for organizations to understand how these changes will impact their operations and user experience.
As organizations prepare for this migration, they are urged to communicate with their teams about the upcoming changes. The New Outlook is designed to create a more efficient and modern workspace, aligning with the evolving demands of businesses today.
Microsoft’s commitment to enhancing user experience through the New Outlook reflects the company’s broader strategy of integrating advanced features into its productivity tools. By making this transition, Microsoft aims to ensure that its users are equipped with the best tools available to manage their communication and scheduling needs effectively.
The New Outlook represents a significant step forward in Microsoft’s vision for a more connected and productive workplace. As the transition date approaches, users and organizations will need to stay informed and engaged with the changes to maximize the benefits of this new application.
In summary, starting April 2026, Microsoft 365 Enterprise users will be automatically switched to the New Outlook for Windows, with the option to revert back to the Classic Outlook. This change is part of Microsoft’s ongoing efforts to enhance user experience and provide a modern, efficient email and calendar solution that meets the needs of today’s organizations.
