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

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

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

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

Current status: We’re progressing with our restarting of controlled services across the impacted environments which is expected to remediate the impact. Our restart timeline projects that the process will have completed and for impact to be remediated by our next scheduled communication update.<\/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 be impacted. This information may be updated as our investigation continues.<\/p>\n

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

Root cause: A service-to-service authentication certificate was recently updated and is disrupting how licensing information is validated, causing some requests to be incorrectly identified as unlicensed and resulting in impact.<\/p>\n
