Microsoft says Outlook and other Microsoft 365 services are slowly improving, but the recovery remains uneven more than 15 hours after the outage began. In its latest update, the company said repair work is moving forward in stages across its infrastructure, and data from its systems and customer reports show gradual gains in several services. However, performance still varies, and capacity has not yet returned to normal levels. Network and traffic management measures remain in place. To protect email during the recovery, Microsoft is giving priority to clearing queued and delayed messages. It has also extended the email timeout window to 48 hours, which means emails stuck in the system should still be delivered rather than bounced or lost. Microsoft has not yet said when full service will be restored.
