Latest official update · User impact: Users may be unable to connect to multiple Microsoft 365 services. More info: Potentially impacted services include: - Exchange Online - Microsoft Teams - SharePoint Online - Microsoft Copilot 365 - Microsoft Defender XDR Current status: We're aggressively pursuing all pathways to reduce impact. As a precaution, we've paused all deployments and configuration changes while we review recent changes for any correlation to this event. We've determined that the elevated load isn't driven by an overall increase in traffic, but by a large number of servers being unexpectedly unavailable, which is shifting load onto the remaining infrastructure. We're investigating what's causing these servers to become unavailable while we work to safely return them to service. Scope of impact: This issue may affect users attempting to access the affected Microsoft 365 services. Next update by: Thursday, November 12, 2026, at 10:00 PM UTC
