Latest Message<\/th>\nTitle: Users may experience issues when trying to access services that require Multi-Factor Authentication (MFA)<\/p>\n

User impact: Some users may experience issues accessing Microsoft 365 services, particularly during sign\u2011in or authentication.<\/p>\n

Current status: We\u2019re reviewing Microsoft Entra sign\u2011in logs and related network telemetry following reports of 504 gateway timeout errors affecting sign\u2011in using Multi-Factor Authentication (MFA) for Microsoft 365 services. In parallel, we’re also analyzing third-party authentication dependencies and interactions to better understand the potential source of the issue.<\/p>\n

Scope of impact: This issue may affect any user within your organization leveraging MFA for sign-in. We’ve confirmed the following region(s) are impacted by this issue: North America. Additional impacted region(s) may be included as our investigation continues.<\/p>\n
