User impact: Admins and users may be unable to access or utilize multiple features within some Microsoft 365 services. <\/p>\n

More info: Specifically, Microsoft 365 for Education services, Microsoft Teams, and Microsoft 365 admin center are impacted and all the affected scenarios consist of the following:<\/p>\n

-Users cannot access Search Coach and Search Progress in Teams for Education; reports indicate it cannot be added as a Teams tab and existing experiences are failing. Lionel described it as a “near total outage” and later “it just doesn’t work.”<\/p>\n

– Parent\/guardian (“related contact”) information can\u2019t be retrieved through School Data Sync (SDS). Any scenarios depending on related contacts fail.<\/p>\n

-Education admins can\u2019t trigger batch age-gating operations from SDS through the Microsoft admin center.<\/p>\n

– Admins and users can\u2019t access Education configuration pages and see an error message “cannot load page” in Microsoft 365 admin center<\/p>\n

– Admins can\u2019t create or manage Speaker Progress resources using Speaker Progress Graph APIs<\/p>\n

-Admins can\u2019t access or utilize Assignments scenarios that call Related Contacts indirectly. <\/p>\n

Current status: We’ve been alerted through our service monitoring that an issue is affecting all education tenants. We’ve identified that a recent rollout of an authentication configuration is causing failures when processing requests to the listed affected scenarios. We’ve applied a change to the affected configuration and are working on validating that it resolves this issue. <\/p>\n

Scope of impact: Admins and users attempting to access or utilize any of the features listed out in the More info section may be impacted by this event. This section may be updated as our investigation continues. <\/p>\n

Root cause: A recent roll out of an authentication configuration is causing failures when processing requests to the listed affected scenarios. <\/p>\n
