Microsoft Transitions Outlook for Enterprise Users: What to Expect

  • Thread Author
Microsoft has announced a significant transition for enterprise users of its Outlook product—starting in April 2026, Microsoft 365 Enterprise customers will be automatically migrated from the classic Outlook app to the new Outlook for Windows. This move represents a major shift in the way users will interact with their email and calendar services, aiming to modernize their experience with a suite of new features.

What's New in the New Outlook?​

The new Outlook for Windows has been designed with a modern interface and comes packed with features that promise to enhance productivity for its users. Key highlights of this transition include:
  • Copilot Integration: Utilizing advanced AI capabilities, Microsoft Copilot facilitates smarter email composition and scheduling suggestions, taking user experience to the next level.
  • Improved Theming Options: Users will have the ability to customize the interface to match their preferences more closely, fostering a more personalized workspace.
  • Advanced Email Management: Features such as email pinning and snoozing make it easier to manage messages, allowing users to prioritize emails effectively.

Transition Process and Options​

The migration to the new Outlook will be initiated automatically, requiring no administrative action from organizations. Nonetheless, administrators can opt out of the migration process if they desire. This proactive approach gives organizations ample time to prepare, with more than a year’s notice leading up to the transition.
For those who have early access to the new Outlook, the option to toggle back to the classic version will remain available, ensuring that users can switch back if they encounter compatibility issues or unmet needs. This flexibility is crucial for enterprises as they consider the ramifications of adopting what might be a fundamentally different software experience.

Exclusions to the Migration​

While most enterprise users will be migrated, some exceptions exist:
  • Users who have opted out via admin controls will not be switched to the new version.
  • Those with the toggle to revert back hidden by policy will remain on the classic version.
  • Users utilizing perpetual licenses or on-premises accounts are also excluded from the transition.
This careful delineation helps cater to diverse organizational needs, ensuring that those who require stability can maintain their current setups.

The Journey So Far​

The rollout of the new Outlook for Windows has been in motion since August 2023, initially targeting commercial customers. However, it’s important to note that certain features available in the classic version—like Exchange Server support and COM add-ins—are currently absent in the new Outlook. To adapt, organizations using the new Outlook will need to leverage web add-ins, which can involve adjustments in workflows.
Microsoft has committed to supporting the classic Outlook for Windows until at least 2029, underscoring their acknowledgment of the transitional hurdles many users may face.

User Feedback and Continuous Improvement​

Microsoft is keen to gather user feedback during this transition. The ability to submit feedback directly through the app is a smart move, allowing them to fine-tune the experience based on real user demands and challenges. This responsiveness will play a crucial role in making the new Outlook genuinely user-friendly and effective, tailored to meet the needs of modern enterprises.

Conclusion​

For Windows users, the upcoming migration to the new Outlook for Windows acts as a pivotal moment in email and calendar management. With an emphasis on modern features and user customization, Microsoft aims to ensure that users not only embrace the new tool but also find it an improvement over the classic version.
