Microsoft is still scrambling to fully restore services as a massive outage stretched into its second day, disrupting operations at governments, hospitals, and businesses around the world.
The tech giant said in a post on X Friday morning that service availability is improving, but some users may still be affected.
“Some users may still experience intermittent access issues or delayed email delivery as recovery continues,” the company said.
As of Friday morning, Microsoft’s status page still showed “service degradation” for both business and consumer versions of Microsoft 365. The company warned that users may be unable to access several Microsoft 365 services, including Outlook and Teams.
Microsoft said it has found no evidence that malicious activity was at fault and is continuing to investigate the underlying cause of the outage.
The problems began around noon on Thursday. In subsequent updates, Microsoft said it found that a large number of servers had unexpectedly become unavailable, “straining the remaining infrastructure.”
Microsoft subsequently determined that a process responsible for establishing secure connections was becoming overwhelmed, causing servers to stop responding. The company has since rolled out a patch to improve server stability, but has not established the underlying cause of the problem.
“We’re seeing encouraging recovery progress, with service availability and email delivery performance improving across a growing portion of affected infrastructure,”
