    Hi @BP

    According to Microsoft's notification (Incident ID: MO1550821), users may be unable to connect to or access multiple Microsoft 365 services, including Exchange Online, Microsoft Teams, SharePoint Online, Microsoft Copilot, and Microsoft Defender XDR.

    Microsoft has identified that the affected infrastructure is experiencing elevated load across multiple regions, which is likely contributing to the connectivity errors. Microsoft is currently restarting and repairing impacted portions of the infrastructure to restore capacity. Additionally, they are investigating an unexpected increase in a specific type of service traffic and evaluating options to redirect traffic to alternative infrastructure to expedite recovery.

    User's image

    The incident is currently classified as Service Degradation, and Microsoft is actively investigating and working to mitigate the issue.

    • If you have Microsoft 365 administrator privileges, please sign in to the Microsoft 365 Admin Center using this link to view the details of this issue.
    • If you are an end user: you can check the Microsoft 365 Service Status for the latest service availability updates.

    I'll continue to monitor this incident and share further updates as soon as Microsoft provides new information.
