Update - Update from Microsoft as of 5:27pm:
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.
What this means: Microsoft is actively working on fixes for the issue, but have so far been unsuccessful in stabilizing the effected services

Update - From an Ariat and client standpoint this seems to be having the most impact on Scan-to-Email functionality, email delivery delays, and Teams.

Identified - Current status: We're carefully rebalancing traffic across all affected infrastructure in the region, while monitoring the corresponding health telemetry, to ensure the environment enters into a balanced state as our remediation efforts continue. We’re proceeding as quickly as possible and this incremental approach will also help us identify whether any additional actions may be required to ensure longstanding recovery.

Update - Microsoft has identified the issue and has issued the following statement:
User impact: Users may be seeing degraded service functionality or be unable to access multiple Microsoft 365 services.
More info: Users may be receiving a "451 4.3.2 temporary server issue" error message when attempting to send or receive email through 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 heathy 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 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 dependent service infrastructure in the North America region isn't processing traffic as expected.
They still have the status as "degraded" and services are still experiencing issues
