As The Register reported yesterday, the outage started on Thursday at around 18:00 UTC and saw Microsoft 365 users unable to access email, attend Teams meetings, use cloud PCs, consult Copilot, or enjoy full access to another 15 hosted services. The software giant says the outage impacts Microsoft 365 services “that interact with Exchange Online and email services.”
Services that don’t need Exchange Online remain functional. The software giant initially blamed the outage on a mysterious “problem that's causing servers to fail automated health checks and become unavailable.”
Microsoft thought it found a fix but quickly admitted “Actions taken thus far have not provided the anticipated relief.” In the hours since, the situation has not improved markedly, and Microsoft is still struggling to restore service. It’s also using changed the language it uses when discussing the possibility a cyberattack is the reason for the outage.
