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: Our efforts to unblock and reprocess the impacted URLs have completed, yet when analyzing the telemetry we’ve detected a few errors that indicate that some of the URLs may not have completed this process as anticipated. We’re analyzing samples of URLs that are seeing continued impact to determine if any additional actions are needed to fully alleviate impact.<\/p>\n

Scope of impact: Any user receiving email messages 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: Saturday, September 6, 2025, at 9:00 AM UTC<\/td>\n<\/tr>\n
