Microsoft's flagship software services remain down, leaving users unable to access email and chat features—one of the company's most serious failures in recent years. On Friday, users around the world reported problems with Outlook, Teams, and the Copilot AI tool; a day earlier, many users in the United States had already been unable to use these services. The tracking platform Downdetector received roughly 200,000 reports of related user issues, making this one of the company's most severe service failures, as previous outages rarely lasted more than a few hours.
