Microsoft has warned of an MFA issue affecting some Microsoft 365 users, blocking access to certain applications and disrupting essential operations.
Microsoft announced the issue through its official MSFT365 Status account on X, stating:
“We’re investigating an issue where Multi-Factor Authentication (MFA) may block access to some Microsoft 365 (M365) apps. Traffic has been redirected, and service availability is improving.”
Administrators were advised to check incident ID OP978247 in the Microsoft admin center for updates and support.
Microsoft Warns of MFA Issue
Multi-factor authentication, a key security measure, adds a layer of identity verification through methods like text, calls, or app verification after a password.
The issue is disrupting multi-factor authentication, blocking access to apps like Outlook, Teams, and SharePoint.
Microsoft is redirecting traffic, showing early signs of improvement, but the cause remains unknown.
The outage affects organizations relying on M365 for communication, collaboration, and workflows, leaving MFA-enabled users locked out and unable to access meetings, emails, or documents.
IT administrators face added pressure to maintain team connectivity while upholding security protocols.
Businesses handling sensitive data may remain extra cautious, as MFA is key to preventing unauthorized access.
Microsoft is actively investigating and mitigating the issue, urging users to check the Microsoft 365 admin center for updates on OP978247.
Traffic redirection has improved some services, but users should prepare for possible delays until the issue is fully resolved.
