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 including specific URLs may have been incorrectly flagged as phishing and quarantined in Exchange Online.<\/p>\n

Final status: Our extended service monitoring has confirmed that following our removal of affected messages from quarantine and their delivery to intended recipients, impact has been remediated.<\/p>\n

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

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

End time: Friday, June 21, 2024, at 10:00 PM UTC<\/p>\n

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

Next steps:
– We’re further analyzing the offending service update to better understand the problems it produced to the domain creation dates and so we can help identify similar issues during our pre-deployment testing and validation processes. <\/p>\n

We’ll provide a Post-Incident Report within five business days.<\/td>\n<\/tr>\n
