Global access crisis at Microsoft: Outlook and 365 services have been disrupted for hours

Microsoft’s Outlook and Microsoft 365 services suffered a widespread access disruption that began on November 12 and continued into the morning of November 13, with outage reports exceeding 130,000 at the peak. The company reported partial recovery, but it had not confirmed that the incident was fully resolved. The disruption matters because Outlook and Microsoft 365 are core productivity tools for businesses, so prolonged outages can interrupt email, collaboration and daily operations for large numbers of enterprise users. Investors and customers will watch for Microsoft’s full confirmation that service has been restored and for the company’s explanation of the root cause.
