    User impact: Users may be unable to connect to multiple Microsoft 365 services.

    More info: More info: Potentially impacted services include:
    - Exchange Online
    - Microsoft Teams
    - SharePoint Online
    - Microsoft Copilot 365
    - Microsoft Defender XDR

    - 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.

    Current status: We're continuing to work through restarting and validating the affected servers to safely return them to service, and we're exploring opportunities to expedite this process. In parallel, we're assessing whether reverting the small number of recent configuration updates we identified could help accelerate recovery.

    Previous status: We've validated an alternative health check method on a subset of affected infrastructure, which allowed the servers in that subset to successfully return to service, and we're now applying this change more broadly. We're also preparing an automated recovery process to continually detect and restart unresponsive servers, to help keep them in service while this change progresses. Additionally, our review of recent changes has identified a small number of configuration updates that we're investigating as potential contributors to the issue.

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