Microsoft has begun reporting improvements in server stability following a global outage that disrupted multiple services, including Outlook, Teams, Microsoft 365, SharePoint and Copilot. The company is applying technical fixes and gradually restoring affected infrastructure, though it acknowledges that full service recovery has not yet been achieved.
In an update published on Friday, 13 November, Microsoft said it had achieved positive results after correcting a configuration component related to authentication and connection routing on its servers.
The remediation effort is being extended across the infrastructure supporting the affected regions. According to Microsoft, as cited by TVI Notícias, monitoring data and customer reports indicate improvements across several services, although system capacity has not yet returned to normal levels.
The outage began on Thursday, 12 November, causing access and connectivity difficulties across multiple regions worldwide. The incident primarily affected Exchange Online, the service underpinning Outlook’s corporate email functionality, but also impaired features across other Microsoft tools.
According to the Associated Press, the Downdetector platform recorded approximately 130,000 problem reports related to Outlook at the peak of the incident. Difficulties accessing Teams, Copilot and other services were also reported, though some features within those platforms remained operational.
Microsoft identified problems in processes responsible for establishing secure connections, which became overloaded and prevented multiple servers from responding normally to user requests.
The unavailability of part of this equipment increased pressure on the remaining servers, compounding access difficulties. To restore services, the company has been rerouting traffic, restarting affected systems and incrementally applying configuration changes to its infrastructure.
Microsoft said it had not identified, as of the time of its update, any evidence of malicious activity associated with the incident. The company committed, however, to continuing to monitor the situation and to publishing a post-recovery report detailing the root cause of the outage and the measures to be taken to prevent similar occurrences.
Microsoft is also managing emails whose delivery was delayed during the outage, extending the retention period to 48 hours before a delivery attempt expires. The measure is intended to reduce the risk of pending messages being lost while recovery operations are under way.
Despite the improvements recorded, the company continues recovery and monitoring operations and has not announced a definitive timeline for full service restoration.
