Microsoft 365 Outage Update: Email Services Largely Restored — November 13, 2026 1:00 PM EST
Friday, November 13, 2026 | Afternoon Update
Current Status: Broad Recovery — Continued Monitoring
Network Solutions and Optimization (NSAO) is pleased to report significant improvements in Microsoft 365 and Outlook email services following the widespread outage that began Thursday, November 12, 2026.
Microsoft has confirmed broad recovery and improved stability across its services. Many users are now able to access Outlook and resume normal email communications.
While Microsoft has not yet officially declared all affected services fully restored, the situation has improved substantially.
What Microsoft Has Confirmed
According to Microsoft's public Service Health Status page, the company has identified the underlying technical issue and implemented corrective measures.
Microsoft reports that the disruption resulted from an issue during an earlier network capacity upgrade that surfaced following a subsequent network change.
Microsoft has addressed the underlying issue and is continuing to restore services to remaining affected customers and regions.
Because of the scale of the disruption, Microsoft is bringing services back gradually while validating stability throughout the recovery process.
Microsoft has also stated that the incident was not related to a cyberattack or artificial intelligence systems.
What NSAO Is Seeing
NSAO has been actively testing Outlook connectivity and email delivery.
We are seeing encouraging results:
Previously delayed emails are arriving in Outlook.
New test emails are being successfully delivered within approximately one minute.
Outlook connectivity has improved substantially.
Normal email communications appear to be returning across affected environments.
These results are consistent with Microsoft's reported recovery progress.
However, customers may still experience occasional delays or intermittent issues as Microsoft completes restoration.
Important: Check for Delayed Emails
Because the outage affected email delivery for an extended period, we encourage customers to review their inboxes for messages that may have arrived later than expected.
We recommend:
Check your Outlook inbox for emails sent during the November 12 outage.
Verify that you can both send and receive new messages.
Review important business communications that may have been delayed.
Follow up by telephone or text if you are unsure whether a critical message was delivered.
Contact NSAO if Outlook continues to experience connectivity or synchronization problems.
Please avoid deleting Outlook profiles or making unnecessary configuration changes to address issues related to this Microsoft service disruption.
NSAO Is Returning to Normal Communications
With significant improvements in email service, NSAO is transitioning from emergency outage notifications to continued monitoring.
We will maintain an incident record on our public service status page until Microsoft confirms full restoration and we are satisfied that services are stable.
