Many of my co-workers have been kicked out of outlook and unable to get back in. Is there an outage of some sort?

    Hello @Sunda Liparoto and everyone,

    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 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.

    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're not an admin and 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    

    Alternatively, follow these steps:

    • 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.

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

    Kind regards.

    We are having the same issue across multiple tenants. Unresponsive admin center, no email or email delay.

    From Microsoft:

    Microsoft 365 Status

    @MSFT365Status

    1h

    We determined the elevated load isn't driven by an increase in traffic, but by a number of servers being unexpectedly unavailable; straining the remaining infrastructure. We're working to safely return them to service. More info under EX1550543 and MO1550821 in the Microsoft 365 admin center, as well as status.cloud.microsoft if the admin center is not available to you.

    Microsoft 365 Status

    @MSFT365Status

    1h

    We're testing a configuration change to address a problem that's causing servers to fail automated health checks and become unavailable. In parallel, we've initiated a restart of all affected servers and are monitoring health as they return to service. More info under EX1550543 and MO1550821 in the Microsoft 365 admin center, as well as status.cloud.microsoft if the admin center is not available to you.

    There are current indications of an Outlook/Microsoft 365 disruption today, November 12, 2026, but your Microsoft 365 tenant’s Service health dashboard is the authoritative place to confirm whether your organization is affected.^1^

    Check your organization’s status

    A Microsoft 365 administrator should:

    1. Sign in to the Microsoft 365 admin center.
    2. Go to Health → Service health.
    3. In Overview, check Exchange Online and Office on the web.
    4. Open any incident or advisory matching forced sign-outs or sign-in failures. The details provide the affected services, user impact, current status, and Microsoft’s latest mitigation updates.^2^

    Service Support administrators and Helpdesk administrators can also view Service health. If nobody can access the admin center, use Microsoft’s public service-status page. Public user reports are also elevated for Outlook, although third-party reports do not confirm that a particular tenant is affected.^3^

    What to do next

    • If an incident is listed: Monitor its updates and avoid resetting multiple users’ passwords or rebuilding Outlook profiles unless Microsoft specifically directs you to do so. Microsoft posts investigation, mitigation, recovery, and resolution updates in the incident.
    • If no incident is listed: In Health → Service health, select Report an issue and submit the organization-wide sign-in symptoms. Microsoft correlates reports across tenants and adds an incident or advisory when the problem is service-side.^2^
    • Because several coworkers were disconnected simultaneously, check service health before doing workstation-level Outlook repairs; Microsoft specifically recommends this when multiple users are reporting Microsoft 365 email problems.^4^

    We are experiencing the same issue. Unfortunately, we cannot access our admin center. I suppose the issue extends to that portal on the web as well.
