Latest Message<\/th>\nTitle: Some users’ URL links in multiple Microsoft 365 services may not be evaluated by Safe Links as expected<\/p>\n

User impact: Users’ URL links in multiple Microsoft 365 services may have not been evaluated by Safe Links as expected.<\/p>\n

More info: This issue could have affected any user within an organization that leverages Safe Links. Users accessing links in Exchange Online, Microsoft Teams, Copilot, and Microsoft 365 for the web may have been affected.<\/p>\n

Final status: We identified that a recent service update intending to improve authentication efficiency for Safe Links introduced an authentication component misconfiguration, resulting in impact. We reverted the change and monitored the environment to validate that the impact was remediated.<\/p>\n

Scope of impact: This issue may have impacted any user clicking URL links in Exchange Online, Microsoft Teams, Copilot, and Microsoft 365 for the web.<\/p>\n

Start time: Wednesday, July 16, 2025, at 9:13 AM UTC<\/p>\n

End time: Tuesday, July 29, 2025, at 3:10 AM UTC<\/p>\n

Root cause: A recent service update intending to improve authentication efficiency for Safe Links introduced an authentication component misconfiguration, resulting in impact.<\/p>\n

Next steps:
– We’re evaluating our service update procedures to better identify similar functionality issues prior to their implementation.<\/p>\n

This is the final update for the event.<\/td>\n<\/tr>\n
