Microsoft software, which includes widely used email and communication tools like Outlook and Teams, has been hit by a global outage since Thursday evening. The company says it has nothing to do with a cybersecurity breach. Hundreds of millions of people use the affected apps daily for their work, making this potentially the “most severe technology outage in history”, a tech analyst told the BBC. Dutch users of Outlook, Teams and Microsoft 365 were still impacted on Friday morning.
