Latest Message<\/th>\nTitle: Some users’ legitimate inbound email messages are being marked as spam and quarantined in Exchange Online<\/p>\n

User impact: Users’ legitimate inbound email messages are being marked as spam and quarantined in Exchange Online.<\/p>\n

More info: Impact is specific to email messages containing bit.ly URL links.<\/p>\n

Current status: We’ve completed our review of the Machine Learning models and added the impacting URL domains to our allow lists. We’re working with affected users to confirm this has remediated impact.<\/p>\n

Scope of impact: Impact is specific to a subset of users receiving email messages containing the affected URL domain via Exchange Online.<\/p>\n

Start time: Monday, May 15, 2023, at 8:17 PM UTC<\/p>\n

Root cause: A logic error in our automated anti-spam algorithm caused it to identify some links to a specific domain within the affected email messages as harmful, leading to impact.<\/p>\n
