Microsoft has resolved an outage after users were unable to access certain Microsoft 365 apps due to issues affecting multi-factor authentication (MFA).
The tech giant took to social media to explain that it was investigating an issue relating to its MFA.
The post said, “We're investigating an issue in which Multi-Factor Authentication (MFA) may prevent users from accessing some Microsoft 365 (M365) Apps.”
