Microsoft Outlook and 365 outage stretches past 12 hours
Microsoft has acknowledged that fixes it applied to resolve ongoing Outlook and Microsoft 365 service disruptions have not worked as intended. The company says it is now exploring alternate approaches to increase system capacity amid persistent traffic management issues, with updates posted under incident codes EX1550543 and MO1550821 in the Microsoft 365 admin center.
GoKawiil's interpretation of the reporting above, not reported fact.
A disruption lasting more than half a day signals that the underlying infrastructure problem is more complex than a routine fix, since Microsoft's first attempted remedy failed. Organizations relying on Outlook and 365 for core business communication could face extended productivity losses the longer the issue persists, and the need for 'alternate workstreams' suggests engineers are still diagnosing the root cause rather than simply restoring service.
- Microsoft Outlook and 365 have been down for over 12 hours
- Initial fixes applied by Microsoft failed to resolve the issue
- Microsoft is now seeking alternate solutions to address capacity and traffic problems
