Latest Message<\/th>\nTitle: Some users may be unable to authenticate to Microsoft 365 apps via My Apps<\/p>\n

User impact: Users may have been unable to authenticate to Microsoft 365 apps through My Apps.<\/p>\n

More info: Affected users may have seen issues while using Microsoft 365 apps through the My Apps Single Sign On (SSO) method (myapplications.microsoft.com\/<\/a>). When authenticating with SSO, impacted users may have received a message stating, “Something went wrong… Authentication error”.<\/p>\n

Final status: After a period of extended monitoring, we\u2019ve confirmed with service health telemetry and previously affected users that reverting the recent change resolved the issue.<\/p>\n

Scope of impact: This issue could have potentially affected any user that attempted to authenticate to Microsoft 365 through the My Apps Single Sign On (SSO) flow. <\/p>\n

Start time: Wednesday, January 22, 2025, at 7:16 PM UTC<\/p>\n

End time: Wednesday, January 22, 2025, at 9:40 PM UTC<\/p>\n

Root cause: Due to a recent configuration change, some service traffic routing data intended for specific internal endpoints became stale. When a SSO service call hit an affected endpoint, the request wasn’t successful and caused an authentication error for the user.<\/p>\n

Next steps:
– We’re evaluating the impacting configuration change to understand how this issue wasn’t identified during our pre-deployment checks so we can avoid similar issues in future updates.<\/p>\n

This is the final update for the event.<\/td>\n<\/tr>\n
