Hi Deborah,

Please be advised that Outlook is currently experiencing a service disruption (Incident ID: MO1550821), categorized under Service Degradation. While Microsoft’s engineering teams are actively investigating and deploying mitigation measures to restore full functionality, an official Estimated Time of Arrival (ETA) has not yet been provided.

For real-time status tracking and timeline announcements, your IT administrator can view the incident directly in the Service Health portal:

https://admin.cloud.microsoft/#/servicehealth/:/alerts/MO1550821

Should you need assistance identifying your organization's administrator, please see: How can I find my Microsoft 365 admin? - Microsoft Support

Microsoft has not published a guaranteed restoration time for the current Outlook/Microsoft 365 disruption; the latest reported milestone is a status update scheduled for November 13, 2026, at 5:30 AM GMT+7, which is an update time—not a commitment that service will be restored by then.^1^

Microsoft 365 business or work account

Ask your Microsoft 365 administrator to check the tenant-specific incident:

Sign in to the Microsoft 365 admin center.
Go to Health → Service health.
Open Active issues Microsoft is working on.
Select the Outlook/Exchange Online incident to review its status, user impact, latest update, and recovery progress.

Microsoft posts ongoing investigation, mitigation, and resolution updates on that incident page. Administrators assigned the Service Support admin or Helpdesk admin role can also view Service health.^2^

To receive updates automatically, the administrator can open the incident, select Manage notifications for this issue, and configure email notifications. Because this is a service-side incident, changing Outlook profiles or reinstalling the client is unlikely to restore access while multiple connection methods are affected.

Personal Outlook.com account

Monitor Microsoft’s public service-status page for recovery announcements.^3^ Microsoft Support also directs Outlook.com users experiencing access problems to that status page.^4^

If the public page reports the service as restored but your mailbox remains unavailable, use Help in Outlook.com and continue to Still need help? → Yes to contact Outlook.com support.
