Latest Message<\/th>\nTitle: Users’ legitimate inbound email messages containing specific URLs are being incorrectly marked as phish<\/p>\n

User impact: Users’ legitimate inbound email messages containing specific URLs are being incorrectly marked as phish.<\/p>\n

Current status: We’ve removed the signatures that were causing our anti-spam process to quarantine the affected email messages, preventing additional inbound email from being incorrectly marked as phish. Subsequently, we’re replaying the affected messages to remove them from quarantine and completely remediate impact.<\/p>\n

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

Root cause: Our automated anti-spam procedure is incorrectly blocking email messages that contain specific URLs, which is causing inbound email messages to be marked as phishing and quarantined due to signatures which are flagged as malicious.<\/p>\n
