Product transitions to the cloud.microsoft domain – September 2025
Microsoft Teams is transitioning to the secure cloud.microsoft domain by September 2025, enhancing security with Microsoft’s exclusive top-level domain. Users will be auto-redirected with no action needed. Admins should update references, educate users, and ensure network access to *.cloud.microsoft. Compliance impact is minimal.
As part of this transition, Microsoft Teams is now available at https://teams.cloud.microsoft, in parallel with its previous domain. This change enhances security by using Microsoft’s exclusive top-level domain, .microsoft, which helps prevent spoofing and builds user trust.

- The cloud.microsoft domain has been a part of standard Microsoft network guidance on domains and service endpoints since April 2023.
