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.

    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^

    Hi everyone,

    According to Microsoft's latest notification, recovery efforts are progressing in phases across the affected Microsoft 365 infrastructure. Global telemetry and customer reports indicate gradual improvements across several services. However, service availability remains inconsistent, and system capacity has not yet fully returned to normal levels.

    Microsoft continues to implement network and traffic-management measures to stabilize the affected services. To protect email delivery during recovery, Microsoft is prioritizing the processing of email queues and backlogs. Additionally, the email timeout window has been extended to 48 hours to help preserve delayed messages.

    Microsoft has confirmed that there is currently no evidence of malicious activity associated with this incident.

    Microsoft will continue the recovery efforts until full mitigation is achieved and will provide a comprehensive Post-Incident Report covering the root cause and preventive measures once the incident is resolved.

    Thank you for your patience and understanding.

    Hi @Sunda Liparoto and everyone,

    I would like to share the latest update regarding the Microsoft 365 service disruption (Issue ID: MO1550821).

    According to Microsoft's latest notification, the incident is now marked as Service Restored. Microsoft has addressed the underlying issue and continues to restore services for the remaining affected customers and regions.

    User's image

    Microsoft has identified the preliminary root cause as an issue during an earlier network capacity upgrade, which surfaced following a recent network change. Due to the scale of demand, services were restored gradually, with stability validated at each stage to ensure a reliable recovery.

    Microsoft has also confirmed that this was a technical issue and was not related to cybersecurity threats or AI/agents.

    A Post-Incident Report will be provided to share further details:

    • Preliminary Post-Incident Report: Within two business days.
    • Final Post-Incident Report: Within five business days.

    If the issue persists, please submit a ticket to request support from Microsoft Technical Team.

    Thank you all for your patience and understanding so far.

    Kind regards.
