Message ID: MC949965
We’re making some changes to the migration from classic Outlook to new Outlook for Windows.
We aim to give more than 12 months of notice to help our customers prepare. Starting April 2026, users with Microsoft 365 for Enterprise licenses will be toggled from classic Outlook for Windows to new Outlook for Windows. Users will be toggled into new Outlook once with this roll-out, with potential to be toggled again in the future. Users will maintain the ability to go back to and use classic Outlook.
Our goal with this change is to give users an opportunity to try new Outlook as millions of users already have. New Outlook gives users the most modern experience with Copilot features, theming, and a wave of valuable time-saving features like Pinning and Snoozing mails. Users are also welcome to give us feedback on new Outlook using Feedback in the Help ribbon, so we can tailor the best email and calendar experience.
[When this will happen:]
General Availability (Worldwide): We will begin rolling out April 2026.
[How this will affect your organization:]
You are receiving this message because our reporting indicates one or more users in your organization are using Microsoft 365 Enterprise licenses.
Users will have notice in the application prior to being toggled and will have the option to opt out of the experience in Outlook Options > General. Users who are toggled into new Outlook can toggle back to classic Outlook if they choose to.
Users will not be toggled if one or more of the following is true:
- You have opted your users out of being automatically toggled per Admin-Controlled Migration to New Outlook
- New Outlook toggle is hidden via policy
- Perpetual license is in use
- On premise account
User-facing article: Switch to new Outlook for Windows – Microsoft Support. We will continue to update this article as we get closer to April 2026.
[What you need to do to prepare:]
This rollout will happen automatically with no admin action required starting April 2026. You may want to notify your users about this change and update any relevant documentation as appropriate. When this change takes effect, if you choose to exclude users from the experience, you can use the following Admin policy to manage new Outlook migration: Admin-Controlled Migration to New Outlook
Later, this policy will also be available via Group Policy Objects (GPO), Cloud Policy, and Intune.

The upcoming migration from classic Outlook to the new Outlook for Windows is set to be a game-changer for both admins and users, and it’s hard not to feel a twinge of excitement about the enhancements on the horizon! As we gear up for this transition, starting in April 2026, let’s take a closer look at what this means for everyone involved.
For users, the switch to new Outlook promises a sleek, modern experience packed with innovative features like Copilot assistance, customizable theming, and time-saving tools like Pinning and Snoozing emails. These upgrades are designed to enhance productivity and streamline daily tasks, making email management smoother than ever. Plus, users will have the option to toggle back to classic Outlook if they feel the need, which is a comforting safety net for those who might be a bit hesitant about change.
On the admin side, the rollout is largely hands-off, which is a relief! With no action required from administrators to initiate this transition, the focus can remain on supporting users and addressing any questions they may have. However, it’s wise for admins to prepare by keeping users informed about the changes and updating any relevant documentation. This proactive approach not only smooths the transition but also fosters a collaborative atmosphere where feedback can be gathered and improvements can be made.
As for the impact of these changes, it’s likely to be significant. The new features are designed to enhance user experience, and the feedback mechanism ensures that Microsoft can fine-tune the Outlook experience based on real user insights. This responsiveness to user needs could lead to increased satisfaction and productivity across the board.
