Latest Message<\/th>\nTitle: Some admins may be unable to access Activity Explorer in the Microsoft Purview portal<\/p>\n

User impact: Admins may have been unable to access Activity Explorer in the Microsoft Purview portal.<\/p>\n

More info: Affected admins may have been unable to load Activity Explorer or may have seen it reporting as unavailable due to licensing checks incorrectly returning ineligible results.<\/p>\n

In some cases, admins may also have experienced issues retrieving sensitivity labels when using the Azure Information Protection (AIP) unified labeling client.<\/p>\n

Final status: Following our restarting of affected services, our internal service telemetry has verified that the impact has been remediated. <\/p>\n

Scope of impact: Some admins attempting to access Activity Explorer in the Microsoft Purview portal or retrieve sensitivity labels using the AIP unified labeling client may have been impacted. <\/p>\n

Start time: Wednesday, April 1, 2026, at 12:00 AM UTC<\/p>\n

End time: Sunday, April 12, 2026, at 8:00 PM UTC<\/p>\n

Root cause: A recent service-to-service authentication component update disrupted how licensing information is validated, causing some requests to be identified as unlicensed and resulting in impact.<\/p>\n

Next steps:
– We’re further analyzing the isolated updated component to help us improve our pre-deployment testing and validations and, in our effort, to prevent similar issues in the future. <\/p>\n

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