Microsoft Outlook outage hits thousands of UK and US users

Microsoft Outlook is experiencing a major outage affecting thousands of users in the UK and around 130,000 in the US, with issues beginning Thursday afternoon and peaking at over 3,300 reported incidents in Britain within 20 minutes. The disruption, which started after 5:20pm UK time, also impacts Microsoft Teams, Copilot, and OneDrive. Users see a 'Failed to fetch' error, blank inboxes, or cannot send emails, with Microsoft attributing the cause to overloaded infrastructure. Microsoft has begun redistributing connection traffic globally to ease the load, though its status webpage is reportedly failing to load for some users. The company says the issue may affect Microsoft 365 services in any region.
