Latest Message<\/th>\nTitle: Some users\u2019 email messages including specific URLs may be being flagged as phishing and quarantined in Exchange Online<\/p>\n

User impact: Users’ email messages including specific URLs may be incorrectly flagged as phishing and quarantined in Exchange Online.<\/p>\n

Current status: We\u2019re in the process of developing a long-term solution to resolve this issue. During this development, we\u2019re validating some manual changes to our detection rules that should prevent the affected domains from being identified as newly created and remediate the impact.<\/p>\n

Scope of impact: Any user with messages including the URLs with the affected domains may be impacted by this event.<\/p>\n

Root cause: A recent change caused domain creation dates to be identified as newly created, which is causing reputation issues with our phishing detection systems, and any messages containing the URLs with the affected domains are being flagged as phishing and quarantined.<\/p>\n
