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 include, but are 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<\/p>\n

Current status: We\u2019ve determined that the Data Classification Service (DCS), which multiple services leverage for actions such as Sensitivity labelling, Data Loss Prevention (DLP) policy applications and Copilot grounding, is not routing requests to active components correctly, resulting in impact. We\u2019re currently investigating why this is occurring and developing a mitigation strategy.<\/p>\n

Scope of impact: Impact is specific to some users located in North America and Europe, attempting to perform any action on files within Copilot.<\/p>\n
