    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
    - Microsoft Planner
    - Microsoft To Do
    - Microsoft Intune

    - Microsoft Purview: Multiple Purview services including Authorization, Auto Labelling, Data Loss Prevention (DLP), Communication Compliance, and Data Classification are impacted.
    - Power BI: All users may intermittently be unable to export reports with MIP sensitivity labels to PDF in Power BI.
    - Microsoft 365 Apps Admin Center: Multiple services including Cloud Update, Cloud Policy, and Inventory.
    - Universal Print: Users may encounter errors submitting print jobs or using admin features.

    Current status: While the servers we've returned to service initially remain healthy, we've observed that they can become unresponsive again once they begin receiving traffic. We're analyzing diagnostic data from these servers with our networking and platform experts to determine what's triggering this behavior.

    Building on the protective traffic management measures we've implemented, we're also temporarily limiting which types of traffic can reach the affected infrastructure in specific locations. This will help us determine whether a particular type of request is contributing to the impact and allow us to restore service incrementally. Additionally, we're rebuilding a subset of affected servers using a previous software configuration to validate whether this prevents them from becoming unresponsive, and we'll expand this approach to additional servers if we observe positive results.

    Previous status: We've begun returning a portion of the affected servers to service, and they're remaining stable so far. We’ve also shifted traffic and connections to alternative pathways wherever possible and have observed limited recovery in some regions.

    We've streamlined our recovery process to expedite returning the remaining affected servers to service. To further support recovery, we're implementing protective traffic management measures in a specific location to reduce load on the affected infrastructure, and we'll expand these measures to additional locations if we observe positive results. As capacity is restored, users may experience a gradual recovery as their clients reconnect to the service.

    Scope of impact: This issue may affect users attempting to access the affected Microsoft 365 services.
