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\u2019re continuing our investigation into an issue impacting enterprise submission processing and have taken actions to stabilize the service. Submission flow has recovered, and we\u2019re closely monitoring the environment to ensure processing continues normally while we work on additional steps to prevent recurrence.<\/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
