The Microsoft service outage, which began by disrupting office operations in over 70 countries worldwide, has now lasted over 12 hours and is still not fully recovered. Microsoft reported that regarding this outage, which started on Thursday, November 12, they have only achieved "minor success" and partial recovery across the affected regions.
The main reason for the prolonged delay in resolving this crisis has been the instability of the initial repair efforts undertaken by the company. Microsoft has stated that as users reconnect to restored server systems, they quickly go offline again, and their initial remedies are "not working as expected."
The company has confirmed that this is not the result of a cyber attack, identifying "excessive capacity load" across server systems and imbalances in managing continuous data congestion as the causes. A specific timeline for full service restoration has not yet been announced, and engineers are currently limiting access to systems, rolling back configuration changes, and experimenting with alternative methods to increase capacity.
Due to this technical glitch, key office applications such as Outlook, Microsoft Teams, and Copilot are still severely disrupted in over 70 countries. Additionally, users have experienced significant difficulties connecting to the web versions of services like Word, Excel, PowerPoint, OneDrive, and SharePoint.
