Latest Message<\/th>\nTitle: Admins may experience delays or failures for Automated investigations in the Microsoft 365 Defender XDR portal<\/p>\n

User impact: Admins may have experienced delays or failures for Automated investigations in the Microsoft 365 Defender XDR portal.<\/p>\n

Final status: We’ve identified that a recently deployed standard service update contained an error that resulted in impact. To alleviate impact we’ve reverted to a previously working version of the service and have confirmed with service health telemetry that our actions resolved impact as expected.<\/p>\n

Scope of impact: Any admin may have been unable to utilize Automated investigations in the Microsoft 365 Defender XDR portal.<\/p>\n

Start time: Thursday, September 18, 2025, at 10:00 PM UTC<\/p>\n

End time: Friday, September 19, 2025, at 7:00 PM UTC<\/p>\n

Root cause: A recently deployed standard service update contained an error that resulted in impact<\/p>\n

Next steps:
– We’re analyzing the standard service update to determine why the error it contained made it past our check process in an effort to avoid impact like this in the future.<\/p>\n

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