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.
Vole confirmed the problem and redirected traffic to alternate systems to mitigate the impact.
In addition to the MFA issue, the company addressed reports of unexpected crashes affecting 365 apps on Windows Server 2016 devices.
Vole began analysing data to determine the root of these crashes and implement a resolution. This event comes on the back of other 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.
The affected servers were in Western Europe. After implementing fixes and monitoring for an extended period, the company declared that services were stable.
Once touted as a cure for security cancer, two-factor authentication systems have proven hugely problematic as they provide a second tier of software which can go wrong and shut users out.
