[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:
- 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.
- Educate users to recognize and expect cloud.microsoft as a key domain for Microsoft cloud experiences. You can refer them to What is cloud.microsoft? - Microsoft Support for more information.
- If your organizational websites, tools, or other materials reference the old URL, those links will be automatically redirected. However, it’s good practice to update those assets to avoid user confusion.
- Update internal documentation, websites, and tools that reference the old Teams URL.
- Partner with developers of in-house Teams apps (including those used in Outlook and Microsoft 365) to follow guidance in: Action required: ensure your Microsoft Teams apps are ready for upcoming domain changes.
- Confirm that *.cloud.microsoft and *.static.microsoft are not blocked on your enterprise network. Please ensure your configurations adhere to the guidance in Microsoft network guidance on domains and service endpoints.
[Compliance considerations:]
