MC1009916 - New Outlook for Windows and Web: Outlook Newsletters

Updated April 23, 2025: We have updated the timeline below. Thank you for your patience.

Coming soon to new Microsoft Outlook: Newsletters in Outlook enable customers to create, distribute, and track success for their internal email newsletters. This message applies to the new Outlook for Windows and Outlook for the web.

This message is associated with Microsoft 365 Roadmap ID 328282

When this will happen:

Public Preview: We will begin rolling out mid-February 2025 and expect to complete by late April 2025 (previously late March). Rollout will begin in Targeted Release and will proceed to Standard Release.

General Availability (Worldwide): We will begin rolling out early August 2025 and expect to complete by early September 2025.

How this will affect your organization:

After this rollout, users in your organization using the new Outlook for Windows and Outlook for the Web can create professional and engaging email newsletters with a variety of rich elements and leverage built-in tools to manage reader engagement. Readers can discover and subscribe to newsletters that interest them using the new Explore page in the Outlook Newsletters module, accessible in the left-side navigation menu. The new module also includes pages for users to view their drafts.

What you need to do to prepare:

Outlook Newsletters will roll out on the specified date as an opt-in preview, meaning that no users in your organization will have access to the new module without you taking additional configuration steps.

User access to Outlook Newsletters is controlled by the OwaMailboxPolicy. OutlookNewslettersAccessLevel property. The default value of this property is Undefined until you set it explicitly, which will default to NoAccess while Outlook Newsletters remains in Preview. You can use Set-OwaMailboxPolicy to update this property to ReadWrite, ReadOnly, or NoAccess. Users with ReadWrite access can create content in Outlook Newsletters while ReadOnly limits users to accessing content created by others in your organization.

After enabling Outlook Newsletters, you may want to notify your users about this change and update any relevant documentation.
