Microsoft is migrating Microsoft 365 web apps (Teams, Outlook, Microsoft 365) to the unified cloud.microsoft domain and moving the trusted domains list used by TeamsJS to a CDN, requiring developers of embedded apps to upgrade TeamsJS to v2.19+ and update X-Frame-Options/CSP to allow “*.cloud.microsoft”; testing is available now, full operation alongside teams.microsoft.com is expected in June 2024, and apps not updated may fail to render on teams.cloud.microsoft and direct users back to teams.microsoft.com.
