Latest Message<\/th>\nTitle: Some users’ inbound attachment scans may be taking longer than expected to complete in Exchange Online<\/p>\n

User impact: Users’ inbound attachment scans may be taking longer than expected to complete in Exchange Online.<\/p>\n

More info: As some safe attachment scans are getting stuck in a progress state, users’ attachments may not be delivered.<\/p>\n

As a workaround, users can forward the email messages containing undelivered attachments to themselves.<\/p>\n

Current status: We’ve received feedback from affected users that impact persists. We’re analyzing the gathered additional data and logs in an effort to isolate the reason for the persistent impact. In parallel, we’ll soon work directly with affected users to conduct a live troubleshooting sessions to find potential alternative means to remediate impact.<\/p>\n

Scope of impact: Impact is specific to some users who are served through the affected infrastructure.<\/p>\n

Root cause: A recent configuration change to a feature which is responsible for processing attachment scan retries is causing the impact.<\/p>\n
