Monitoring - Update from Microsoft:

User impact: Users may be seeing degraded service functionality or be unable to access multiple Microsoft 365 services.

More info: Users may receive a "451 4.3.2 temporary server issue" error when attempting to send or receive email in Outlook.

Some of the impacted service functions include, but may not be limited to:
- Sending and receiving email through Exchange Online, including notification emails from Microsoft Viva Engage.
- Collecting message traces.
- Searching within SharePoint Online and/or Microsoft OneDrive.
- Accessing the service portals, including Microsoft Purview, Microsoft Defender XDR, and the Microsoft 365 admin center.
- Creating chats, meetings, teams, channels, or adding members in Microsoft Teams.
- Receiving presence or location information in Microsoft Teams.
- Applying and managing sensitivity labels, interactive operations on reports, and artifacts with sensitivity labels in Microsoft Fabric.

Current status: While we've restored the affected infrastructure to a healthy state, further load balancing is required to mitigate persistent impact. We've identified and are implementing additional actions to direct requests and traffic to additional healthy sections of infrastructure to achieve a withstanding recovery.

Scope of impact: Any users served through an affected section of service infrastructure in the North America region may be intermittently impacted.

Root cause: A portion of the dependent service infrastructure in the North America region isn't processing traffic as expected.

Thank you for your patience while Microsoft works to resolve this issue.
