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\u2019ve recovered the majority of the email and Teams messages that were incorrectly flagged as malicious spam for containing affected URLs. We\u2019re continuing to validate the scope of impacted URLs in order to fully address any remaining email and Teams messages. In parallel, we’re working to identify the root cause and any underlying factors to prevent the issue from occurring again and fully mitigate impact.<\/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: Tuesday, September 9, 2025, at 1:00 AM UTC<\/td>\n<\/tr>\n
