MC1396358: Microsoft Edge: Validate Edge builds early with enterprise preview

[What and Why:]

Enterprise Preview in Microsoft Edge introduces a streamlined way for admins to validate prerelease Edge builds directly within the Stable application. This reduces deployment friction and enables faster feedback loops while maintaining user productivity. Admins gain centralized controls and visibility in the Microsoft 365 admin center, allowing them to manage preview participation, monitor their flighting population, and receive recommendations.

This message is associated with Roadmap ID 557185.

[Rollout Schedule:]

• Public Preview (Worldwide): We began rolling out in early February 2026 and expect to complete by mid-June 2026.
• General Availability (Worldwide): We will begin rolling out in mid-June 2026 and expect to complete by mid-June 2026.

[Impact on Your Organization:]

Who is affected: Admins managing Microsoft Edge Update policies and users on devices with Microsoft Edge configured for Beta or Dev channels.

Platforms/Services: 

• Microsoft Edge (Stable application)
• Microsoft 365 admin center
• Edge Management Service

What will happen:

• Users can receive prerelease Edge builds directly within the Stable application. 
• By default, users can opt out of the preview experience when allowed by policy. 
• Built-in rollback enables users to switch between prerelease and Stable versions without reinstalling Edge.
• Admins can configure preview settings, monitor flighting populations, and view recommendations in one place.
• The new EdgePreviewEnrollmentType policy introduces user opt-out control:
  • Allow opt-out: Users can switch between prerelease and Stable channels.
  • Required: Users remain on the configured prerelease channel (similar to previous TargetChannel behavior).
• If your organization currently uses TargetChannel (Beta or Dev), this change enhances flexibility by introducing user-level control.

[Action Required / Recommendations:]

No action is required before rollout.

However, we recommend that admins:

• Review your current Edge update policies (Beta or Dev channels).
• Decide if users should be allowed to opt out:
  • Set EdgePreviewEnrollmentType to Allow opt-out (default behavior)
  • Or set EdgePreviewEnrollmentType to Required to enforce prerelease participation
• Monitor your preview population in the Microsoft 365 admin center or Edge Management Service.
• Communicate the change to IT support teams, especially regarding user opt-out and rollback capabilities.
