Latest Message<\/th>\nTitle: Some users may be blocked from opening URLs in Exchange Online messages and Microsoft Teams<\/p>\n

User impact: Users may be blocked from opening URLs in Exchange Online messages and Microsoft Teams.<\/p>\n

More info: Additionally, admins may receive alerts titled “A potentially malicious URL click was detected involving one user”; however, the URLs have been confirmed as safe.<\/p>\n

Some email messages may have also been incorrectly quarantined.<\/p>\n

Current status: We\u2019ve continued to make progress in reducing the frequency of false positive flagging while identifying new opportunities to improve recovery accuracy. Recovery efforts remain ongoing and require careful attention to ensure that legitimate content is restored appropriately, while malicious items remain securely quarantined. Our analysis of flagged content is actively informing updates to detection logic, helping us drive safer and more complete recovery outcomes. Thank you for your continued patience as we work through this issue.<\/p>\n

Scope of impact: Any user receiving email messages or messages within Microsoft Teams containing specific URLs may be affected.<\/p>\n

Start time: Friday, September 5, 2025, at 1:10 PM UTC<\/p>\n

Root cause: An anti-spam service incorrectly flagged URLs contained within other URLs as potentially malicious, resulting in impact.<\/p>\n

Next update by: Monday, September 8, 2025, at 6:00 AM UTC<\/td>\n<\/tr>\n
