(Updated) Missed Activity Emails for Teams Will Now Come from a Unified Domain [MC1112449]

Updated July 11, 2025: We have updated the content. Thank you for your patience.

To support a more consistent and secure email experience across Microsoft 365, we are transitioning to a unified domain for all product-generated emails. As part of this change, missed activity emails for Microsoft Teams will now be sent from ‘[email protected]’ instead of the previous ‘noreply@*email.teams.microsoft.com’ domain.

[When this will happen:]

• Public Preview: Rolling out early July 2025, expected to complete by early July 2025.
• Targeted Release: Rolling out early July 2025, expected to complete by early July 2025.
• General Availability: Rolling out mid-July 2025, expected to complete by late July 2025.

[How this will affect your organization:]

There is no impact to tenant configuration or admin settings. End users will simply see a new sender address for missed activity emails from Teams. No action is required from users or admins.

[What you can do to prepare:]

No preparation is needed. However, you may wish to inform your helpdesk or communications teams of the sender address change to avoid confusion or misidentification of legitimate messages.
