-Intelligence features such as Copilot.
-Compliance features, such as Auto-Classification and Consumer consent.
-Collaboration features, such as @mentions.
-Identity features such as people cards and the people well.
-Personalization features, such as roaming and most recently used documents.
-Application features such as Present in PowerPoint or PowerQuery in Excel.<\/p>\n

Final status: We’ve completed the reversal of the offending service update and confirmed through service health telemetry that the impact is remediated.<\/p>\n

Scope of impact: Some users attempting to use any of the scenarios mentioned in the “More Info” section may have been impacted.<\/p>\n

Start time: Friday, October 31, 2025, at 6:45 PM UTC<\/p>\n
