Status details: M365 Degraded Service Functionality

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

More info: Some of the impacted service functions include, but may not be limited to:

- Sending and receiving email through Exchange Online, including notification email from Microsoft Viva Engage as well as subscription email for Microsoft Fabric users. Users may be receiving a "451 4.3.2 temporary server issue" error message when attempting to send or receive email through Outlook.

- Collecting message traces in Exchange Online.

- Searching within SharePoint Online, Microsoft OneDrive, and/or Microsoft Teams.

- Accessing the service portals, including Microsoft Purview, Microsoft Defender XDR, and the Microsoft 365 admin centre.

- Creating chats, meetings, teams, channels or adding members in Microsoft Teams. Additionally, some users may be intermittently unable to create breakout rooms or Microsoft Teams live events.

- Receiving presence or location information in Microsoft Teams.

- Existing or new meeting options for Facilitator in Teams may not be honoured.

- Applying and managing sensitivity labels, interactive operations on reports, and artifacts with sensitivity labels in Microsoft Fabric.

- Print registration and printer jobs may fail in Universal Print.

Current status: During our ongoing efforts to rebalance traffic across the region, we introduced a targeted load balancing configuration change intended to expedite the recovery process, which incidentally introduced additional traffic imbalances associated with persistent impact for a portion of the affected infrastructure. We're remedying our load balancing configurations while, in parallel, reviewing the viability of expediting our ongoing incremental rebalancing and recovery efforts.

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 dependent service infrastructure in the North America region isn't processing traffic as expected.
