Microsoft Forms automated email sender domain is changing

Microsoft Forms will change its automated email sender from maccount@microsoft.com to no-reply@forms.mail.microsoft starting mid-August 2026. Admins should update mail flow rules and safe sender lists accordingly. GCC environments get this update from early September 2026. No compliance issues identified.

[What and Why:]

Microsoft Forms will update the email address used for automated notifications from maccount@microsoft.com to no-reply@forms.mail.microsoft. This email address is used for Microsoft Forms automated emails, including response receipts, email notifications for new responses, and Forms response monitoring updates.

For GCC, GCC High, and DoD environments, admins will now have the option to configure notification emails. These notifications will also use no-reply@forms.mail.microsoft, aligning with Worldwide environments.

Bring your own domain (BYOD) email addresses remain supported when configured by a tenant admin. 

[Rollout Schedule:]

• General Availability (Worldwide): Rollout begins in mid-August 2026 and is expected to complete by early September 2026.
• General Availability (GCC, GCC High, DoD): Rollout begins in early September 2026 and is expected to complete by mid-September 2026.
