Missed Activity Emails for Teams Will Now Come from a Unified Domain

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.
