Businesses worldwide increasingly depend on cloud-based services for day-to-day operations, making any disruptions to these platforms a serious challenge.
Microsoft 365, a staple for many organizations, recently experienced an issue with its Multi-Factor Authentication (MFA) functionality, leaving some users unable to access essential applications.
The outage, which affected users relying on MFA for login, also blocked access to MFA registration and reset options.
Product Deactivated Errors
Microsoft confirmed the problem and redirected traffic to alternate systems to mitigate the impact.
This approach allowed engineers time to investigate the cause and work toward a solution, according to Bleeping Computer.
In addition to the MFA issue, the company addressed reports of unexpected crashes affecting 365 apps on Windows Server 2016 devices.
Microsoft began analyzing data to determine the root of these crashes and implement a resolution.
This event comes on the heels of other recent service disruptions for Microsoft 365.
Late last year, a global outage caused widespread service interruptions across tools like Teams, Exchange Online, and SharePoint.
Another incident caused "Product Deactivated" errors for users of Microsoft 365 Office apps, further complicating access for affected customers.
On January 13, Microsoft announced that the issue was resolved, confirming that a section of the infrastructure managing MFA operations had become unresponsive.
The affected servers were located in Western Europe. After implementing fixes and monitoring for an extended period, the company declared that services were stable.
Although the disruption was limited to users authenticating through MFA, it served as a reminder of the importance of reliable infrastructure in cloud-based systems.
