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 are confirmed as safe.<\/p>\n

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

Current status: We’re continuing to monitor the service and replaying any residual impacted messages to ensure full resolution. The service continues to remain in a healthy state and we’re taking additional time to address any lingering impact as needed. We expect this issue will be resolved by our next scheduled update and will continue to closely watch for any signals of changes. <\/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: Wednesday, September 10, 2025, at 6:00 PM UTC<\/td>\n<\/tr>\n
