Microsoft's recovery efforts fall short as Outlook, Teams, and Copilot outages persist

Microsoft is struggling to fix a global outage disrupting Outlook, Teams, OneDrive, and Copilot, with initial recovery measures failing to restore services fully. The company is exploring alternative solutions after its first fixes did not work as expected. The outage stems from unavailable servers that increased workload on remaining infrastructure, overwhelming the secure connection mechanism. Microsoft is testing a new configuration on a limited server group and reversing a recent change that coincided with the disruption's start. Users in the US, Japan, and Singapore reported issues, with Downdetector showing nearly 140,000 Outlook complaints globally. Microsoft warns recovery may be inconsistent, with possible further interruptions even for restored services.
