On the night of July 26, 2026, an internal Microsoft licensing service shared across multiple products — used by Xbox to authenticate sign-ins and entitlement checks — failed. This caused widespread sign-in failures and broke any flow requiring an entitlement check, including listing a player's full game library and launching owned games, both digital and disc-based. The outage affected Xbox Series X/S, Xbox One, and Xbox 360 (including backward-compatible titles), and also disrupted several publishing and store partners who depend on the same shared systems.
Workaround: None available — affected players could not launch owned games, digital or physical, until Microsoft restored the backend service.
Severity: Major (blocked access to purchased games and sign-in for a large user base across all console generations for ~16 hours; no permanent data loss or security exploitation, and the outage was resolved without a fix release).
