Latest Message<\/th>\nTitle: Multiple issues within Microsoft 365 related to data classification and sensitivity service<\/p>\n

User impact: Multiple issues within Microsoft 365 related to Data Classification and Sensitivity labelling services.<\/p>\n

More info: Impacted services included, but were not limited to:
– Exchange Data Loss Prevention (DLP) and Autolabeling
– Endpoint DLP
– OneDrive for Business and SharePoint Online DLP and Autolabeling
– Copilot grounding
– Microsoft Defender for Cloud Apps
– Inline DLP
– Microsoft Purview, including the Microsoft Purview browser extension
– Purview DLP Agent<\/p>\n

Final status: We\u2019ve confirmed recovery efforts were successful, and service health has been fully restored.<\/p>\n

Scope of impact: Impact was specific to some users who were served by sections of infrastructure located in North America and Europe and were attempting to leverage Data Classification and Sensitivity labeling services such as those identified in the More info section above.<\/p>\n

Start time: Wednesday, November 19, 2025, at 2:00 AM UTC<\/p>\n

End time: Thursday, November 20, 2025, at 1:25 AM UTC<\/p>\n

Root cause: A network access policy implementation issue was preventing the Data Classification Service (DCS) from accessing the dependent virtual machines (VMs).<\/p>\n

Next steps:
– We’re reviewing our policy implementation procedures to prevent similar issues from occurring in the future.<\/p>\n

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