Latest Message<\/th>\nTitle: Admins may encounter delays of up to 10 hours for grading results on Microsoft Defender for Office 365 submissions page <\/p>\n

User impact: Admins may encounter delays of up to 10 hours for grading results on Microsoft Defender for Office 365 submissions page. <\/p>\n

Current status: We’ve identified that an increase in requests has caused a section of infrastructure, responsible for processing email submission grading, to perform below acceptable performance thresholds resulting in impact. We’re applying performance optimizations to improve processing capacities to remediate impact. <\/p>\n

Scope of impact: Impact is specific to any admin served through the affected infrastructure expecting email submission grading. <\/p>\n

Root cause: An increase in requests has caused a section of infrastructure, responsible for processing email submission grading, to perform below acceptable performance thresholds resulting in impact. <\/p>\n
