Outlook Outage

Check Microsoft 365 admin center → Health → Service health → Exchange Online for the incident affecting your tenant and Microsoft’s latest restoration update; no verified universal restoration time is currently available.

Current reports indicate an Outlook/Microsoft 365 connectivity disruption around November 12–13, 2026, consistent with Outlook remaining disconnected for several hours.^1^

Check the incident and restoration status

1. Sign in to the Microsoft 365 admin center with an administrator, Service Support Administrator, or Helpdesk Administrator account.
2. Select Health → Service health.
3. Under Active issues Microsoft is working on, open the Exchange Online or Outlook incident.
4. Review:
   • Status
   • User impact
   • Last updated
   • All updates
   • Any stated mitigation progress or estimated recovery time

Microsoft documents this as the authoritative tenant-specific location for active incidents and restoration progress.^2^

If you cannot access the admin center, check the public Microsoft service status page. If you are not an administrator, ask your organization’s Microsoft 365 administrator or IT department to check Service health for you.

Microsoft normally posts service-incident updates hourly unless the incident notice specifies a different cadence.^3^ An exact recovery time should not be assumed until it appears in that incident record.

If Service health shows no incident

Test Outlook on the web. If webmail works but the desktop application remains disconnected, the issue is probably limited to the client or its connection. Microsoft provides an Outlook connectivity diagnostic for Microsoft 365 administrators and identifies software updates and damaged Outlook profiles as common client-side causes.^4^

If webmail also fails and no incident is listed:

• In Health → Service health, select Report an issue.
• Ask the Microsoft 365 administrator to verify the account, license, and mailbox status.
• If necessary, have the administrator open a Microsoft support request from the admin center.

Avoid resetting Outlook or rebuilding its profile while an active Exchange Online incident is listed; those actions will not accelerate Microsoft-side restoration.
