Microsoft has begun restoring services affected by a major Microsoft 365 outage, with the company reporting improvements in Outlook mailbox access and delayed email processing. The disruption has also affected several other services, including Microsoft Teams, SharePoint Online, Copilot, Microsoft Defender and Planner.
However, the recovery process is still underway, and users may continue to experience intermittent problems accessing these services.
In latest update posted on X, The tech giant said it had completed recovery actions across portions of the affected infrastructure and was gradually restoring traffic. The US-based tech giant said its immediate priority was to extend these recovery measures to the remaining affected infrastructure while stabilising services and adding capacity.
“We’ve made additional progress toward recovery, with actions now completed across portions of affected infrastructure and traffic being gradually restored,” Microsoft said in its latest update.
The improvement comes after users reported problems accessing Microsoft 365 services on Thursday, November 12. The disruption affected Outlook, Microsoft’s widely used email platform, with users experiencing difficulties connecting to their mailboxes and delays in email processing.
The incident also affected access to several other Microsoft 365 services.
Microsoft is tracking the disruption under incident number MO1550821. Its service status advisory says users may be unable to connect to multiple Microsoft 365 services.
While the latest update points to progress in restoring access, the company has not declared the incident fully resolved.
The outage is particularly important for businesses and professionals that depend on Microsoft 365 for everyday communication and workplace operations.
Outlook is used by organisations to manage emails, meetings and calendars, while Microsoft Teams and SharePoint are commonly used for internal communication and collaboration.
Microsoft’s latest update also suggests that restoring individual services is only one part of the recovery process. The company is working to bring the remaining affected infrastructure back online and increase available capacity so that services can handle regular traffic without further disruptions.
