    Dear Kerin Buckerfield,

    I understand your concern. In this case, I would like to share an update regarding the connectivity issue affecting multiple Microsoft 365 services.

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

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

    Regarding the restoration timeline and email delivery, Microsoft will provide official updates through the Service Health dashboard. I would recommend contacting Microsoft 365 business support if the issues persist or require further investigation.

    If you have Microsoft 365 administrator privileges, please sign in to the Microsoft 365 Admin Center to view the details of this issue.

    • Sign in to the Microsoft 365 Admin Center.
    • Go to Health > Service Health.
    • Search for Issue ID: MO1550821.
    • Select the issue and expand the details to review the latest updates, affected services, impact, and remediation information.

    Note: If you don't know who the admin is in your organization, you can find guidance here: How can I find my Microsoft 365 admin? - Microsoft Support    

    I'll continue to monitor this case and let you know if there are any updates.

    Kind regards.

    No public restoration ETA is currently verified for a specifically identified New Outlook for Windows outage; your organization’s Microsoft 365 administrator should check the tenant-specific incident in Microsoft 365 admin center → Health → Service health.

    Check the current status and ETA

    1. Sign in to the Microsoft 365 admin center with a Service Support admin, Helpdesk admin, or another eligible administrator account.
    2. Go to Health → Service health.
    3. Under Active issues Microsoft is working on, open the Outlook or Exchange Online incident matching your symptoms.
    4. Review:
      • Status
      • User impact
      • Last updated
      • All updates, including investigation and mitigation progress
      • Any estimated restoration time Microsoft has published

    Microsoft posts ongoing investigation, mitigation, and restoration updates on that incident page. An ETA may not appear until Microsoft has identified the cause and corrective action.^1^

    If the incident is listed, select Manage notifications for this issue to receive update emails. Admins can also configure broader notifications through Customize → Email.^1^

    If the admin center is unavailable

    Check the public Microsoft service-status page.^2^ The public page may show broadly affecting incidents, but it does not currently provide a confirmed ETA for an incident specifically identified as “New Outlook for Windows business offline.”

    If no incident appears for your tenant

    In Health → Service health, select Report an issue and submit the affected users, start time, client, and symptoms. Microsoft compares reports across organizations and, when a service-side issue is confirmed, publishes an incident or advisory that can then be tracked from the dashboard.^1^

    The exact incident ID is needed to provide a more specific update; without it, there is no supported public ETA to quote.
