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

User impact: Some users’ legitimate inbound email messages with URLs are being incorrectly marked as phish by anti-spam detection.<\/p>\n

More info: We cannot provide the list of affected URLs in detail.<\/p>\n

Current status: We’ve released the bulk of the impacted email messages from quarantine and are monitoring to confirm any remaining messages are released as expected. We anticipate this process may be complete by the time of our next scheduled update.<\/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

Start time: Tuesday, October 29, 2024, at 5:39 PM UTC<\/p>\n

Root cause: A recent rule set change in our automated anti-spam procedure is incorrectly blocking email messages containing certain types of URLs. This change is causing inbound email messages to be marked as phishing and quarantined because some signatures are being flagged as malicious.<\/p>\n

Next update by: Friday, November 1, 2024, at 10:00 PM UTC<\/td>\n<\/tr>\n
