Manage the New Outlook Toggle via Admin Policies
Understand Microsoft's transition plan and use administrative tools to control when users can switch to the New Outlook to prevent unauthorized migration.
New Outlook is Microsoft's intended long-term replacement for both the Windows Mail app and Classic Outlook. It is being introduced to personal and enterprise users alike to unify the email client experience.
While Classic Outlook will remain supported for several years across perpetual and subscription licenses, organizations can prevent unauthorized migration and potential feature loss by managing its availability through centralized admin policies.
Before allowing the switch, review the official feature differences between Classic Outlook and New Outlook to ensure your organization's required workflows are fully supported.
Log in to the Microsoft 365 Admin Center with your global or Exchange administrator credentials and navigate to the Exchange Admin Center.
Adjust the Outlook on the web mailbox policies to either enable or disable the 'Try the new Outlook' toggle for specific groups, users, or your entire organization.

Frequently Asked Questions
Is the New Outlook only replacing the built-in Windows Mail app?
No. While it does replace the built-in Windows Mail application, New Outlook is also designed as Microsoft's long-term replacement for the Classic Outlook desktop client for both personal and enterprise users.

Can individual business users hide the New Outlook button?
In Microsoft 365 Business environments, the visibility of the toggle is typically controlled by your IT department. Administrators must adjust Exchange mailbox policies to hide the button globally or for specific users.
