Microsoft is ushering in a new era for Outlook on Windows with a bold deployment strategy that promises to redefine the user experience for millions of Microsoft 365 subscribers. The tech giant's recent move to include the New Outlook app by default in fresh deployments signals not only a software refresh but also a commitment to a gradual, user-controlled transition away from the Classic Outlook interface.
The New Outlook isn’t just a cosmetic refresh. Equipped with a refreshed design and modern interface enhancements, it aims to deliver improved performance and more intuitive workflows. At the same time, Microsoft has been careful to ensure that the move doesn’t alienate longtime users of the classic version.
• Starting with Version 2502 of the Microsoft 365 Apps—officially rolled out on the Current Channel on March 5—new deployments on Windows devices will include the New Outlook app by default. This update, approximately 60 MB in size and featuring build 18526.20168, marks a significant milestone in Microsoft’s ongoing evolution of its desktop clients.
• For organizations that prefer a careful transition, Microsoft has enabled the option for both Outlook versions to coexist. In its default configuration, both the New and Classic Outlook are installed side-by-side, ensuring that employees can gradually acclimate to the new interface without disruption.
• Business users with Microsoft 365 Business Standard and Premium licenses will start receiving in-app notifications prompting their automatic migration from Classic to New Outlook—beginning in January 2025. However, an important safety net is in place: users can opt out of the switch, and even revert back to Classic Outlook at any time using a simple toggle in the new application. This opt-out option helps ease concerns about an abrupt shift in familiar workflows.
• Prior to the full-scale migration, Microsoft is testing the waters with a Beta Channel deployment for Business plan users as early as November 2024. This phased rollout allows the company to gather valuable feedback and fine-tune the new experience before it becomes the default for all users.
The ability to disable the automatic migration provides organizations with much-needed breathing room to plan their transition schedules. Admins can benchmark user feedback, conduct pilot testing, and roll out training sessions before committing to a full migration. While the New Outlook brings modern design and improved integration with the broader Microsoft 365 ecosystem, administrators have the reassurance of maintaining continuity via the classic interface for as long as necessary.
From an end-user perspective, the innovative design could mean a more intuitive navigation, improved search capabilities, and a more consistent UI across devices. These improvements could be particularly beneficial in a hybrid work environment where seamless collaboration is key.
Interestingly, while many users might appreciate the refined aesthetics and enhanced usability of the new design, there’s always some resistance to change—especially when it comes to tools that are integral to daily productivity. By offering a toggle to switch back to Classic Outlook, Microsoft allows users to ease into the new experience at their own pace, mitigating a common source of frustration during significant software transitions.
The move also foreshadows potential future integrations across the Microsoft 365 ecosystem. With both versions of Outlook able to be managed side-by-side, organizations might find innovative ways to leverage the strengths of each interface. Imagine a scenario where users can switch contexts based on the task at hand—a testament to the flexibility offered by Microsoft’s latest update strategy.
As the deployment date approaches, organizations and individual users are encouraged to explore the nuances of the New Outlook, provide feedback during the Beta Channel phase, and prepare for a future where software evolution is as smooth as it is inevitable. Whether you’re an IT admin orchestrating the transition or a daily user navigating your inbox, this new chapter in Outlook’s storied evolution offers something for everyone—if only you dare to toggle beyond the classic.

A New Chapter in Outlook Evolution
It wasn’t too long ago—back in December 2024—that Microsoft announced via the Microsoft 365 admin center a roadmap for eventually replacing Classic Outlook with the New Outlook. The plan was twofold: enterprise users are slated for a full transition to the new interface by April 2026, while business plan users on the Current Channel are set to begin a phased migration starting January 2025. This staggered rollout strategy reflects Microsoft’s understanding that sweeping changes, especially those affecting essential productivity tools, need to be handled with care.The New Outlook isn’t just a cosmetic refresh.

What This Means for IT Administrators
For IT admins, this isn't just a software update—it’s a strategic shift in deployment management. With administrative control over whether classic, new, or both versions are installed, IT professionals can tailor the transition to suit their organizational needs. This flexibility is especially crucial in environments where change management and user training are top priorities.The ability to disable the automatic migration provides organizations with much-needed breathing room to plan their transition schedules.
