Latest Message<\/th>\nTitle: Some users\u2019 email messages including specific URLs may be 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’ve reviewed the preliminary list of domains and have removed the malicious ones to ensure phishing email messages aren’t released from quarantine. We’ve begun releasing the affected legitimate email messages from quarantine and will monitor this process to ensure all the affected email messages are delivered to their intended destination.<\/p>\n

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

Start time: Tuesday, June 18, 2024, at 8:01 PM UTC<\/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
