So, when will it be usable? The service is currently disrupted—please provide an update as soon as possible.

    Dear @Ari Kurniawan

    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.

    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.

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

    There is no published universal restoration time for the reported Outlook disruption; your organization’s latest status and any estimated recovery time are shown in its Microsoft 365 Service health incident record.

    Check the incident update

    1. Sign in to the Microsoft 365 admin center with a Global Reader, Service Support Administrator, Helpdesk Administrator, or other account permitted to view service health.
    2. Open Health → Service health.
    3. Under Active issues Microsoft is working on, select the Outlook or Exchange Online incident.
    4. Review Status, User impact, Last updated, and All updates. Microsoft posts investigation, mitigation, and restoration progress there. ^1^

    If no matching incident appears, select Report an issue on the Service health page. This submits the tenant’s symptoms for correlation with reports from other organizations.

    Receive updates automatically

    Open the incident and select Manage notifications for this issue to receive email updates. For broader alerts, use Customize → Email, enable service-health notifications, and select the relevant services. ^1^

    If the admin center itself is unavailable, use the public Microsoft service-status page. It can identify broader known outages, but the admin center contains the detailed, tenant-specific incident information. ^2^

    The Classic Outlook known-issues page tracks client defects and workarounds; it is not the authoritative source for live Microsoft 365 service-outage recovery estimates. ^3^
