Microsoft says root cause of outage fixed

Microsoft said the “underlying cause” that caused the global outage “has been fixed,” adding that residual impact is still affecting some services, CNN reported.

“The underlying cause has been fixed, however, residual impact is continuing to affect some Microsoft 365 apps and services,” Microsoft said in a post on X Friday.

“We’re conducting additional mitigations to provide relief,” the post added.

The outage appears to stem at least partly from a software update issued by firm CrowdStrike, experts tell CNN. The CEO of CrowdStrike said that the IT issue causing a global outage has been identified and that a fix has been deployed.
