Product transitions to the cloud.microsoft domain – September 2025 [MC1162275]

Message ID: MC1162275

[Introduction]

To improve security and trust across Microsoft cloud services, Microsoft introduced the cloud.microsoft domain in early 2023. This unified, dedicated DNS domain space hosts Microsoft’s first-party authenticated SaaS products and experiences.

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.

[When this will happen:]

Microsoft Teams is already available at cloud.microsoft. Redirection from the previous domain will begin gradually over the coming months.

[How this affects your organization:]

Who is affected: Admins managing Microsoft Teams, Teams apps, and network configurations. All users accessing Microsoft Teams.

What will happen:

    <a href="https://teams.cloud.microsoft/" targetsoft

  • Users will be automatically redirected to teams.cloud.microsoft.
  • No user action is required; existing links and bookmarks will continue to work.
  • Users may notice that the new application domains are lacking the “.com” extension. This is by design, as “.microsoft” is Microsoft’s own top-level domain – and this exclusivity allows for additional security and protection against spoofing.
  • Admins can disable redirects via the Teams Admin portal if needed.
  • The cloud.microsoft domain has been a part of standard Microsoft network guidance on domains and service endpoints since April 2023. 

[What you can do to prepare:]

[Compliance considerations:]

No compliance considerations identified, review as appropriate for your organization.
