Microsoft Outlook is still experiencing service disruptions for some users in the United States and other countries as Microsoft works to recover from a widespread Microsoft 365 outage. While the company has reported progress, email access and several connected services have not yet returned to normal for everyone.
If Outlook isn’t loading, your emails aren’t arriving, or you keep seeing connection errors, the problem may be on Microsoft’s side rather than with your computer or internet connection.
The disruption began Thursday, November 12, and continued into Friday morning. Microsoft’s public service-health information was still reporting degraded service for Microsoft 365 business customers and consumer products in the latest notices reviewed.
Engineers have reported improvements in server stability and email processing, but Microsoft has not confirmed that all affected customers have regained access. Microsoft Service Health+2
Is Microsoft Outlook Down Right Now?
Yes, Microsoft was still reporting service degradation on Friday morning, November 13, 2026, although the outage was not affecting every user or every Outlook feature.
The company’s status information showed continuing problems involving its business and consumer services. Some users were unable to access email accounts, while others experienced delays or intermittent errors.
Microsoft’s recovery efforts have brought some infrastructure back online, but availability has varied by region and account type.
According to ABC News’ November 13 outage coverage, Microsoft was seeing early improvements in capacity while continuing to restore affected systems.
For users in the U.S., the most useful distinction is whether Outlook itself is experiencing a widespread service problem or whether the issue is limited to a particular account, device or workplace.
How to Check Whether Outlook Is Down
Before changing passwords, reinstalling Outlook or modifying account settings, check whether Microsoft has acknowledged a service disruption.

What Is Wrong With Microsoft Outlook?
Microsoft has linked the disruption to unstable infrastructure supporting Exchange Online, the service responsible for handling email for many Microsoft 365 business customers.
During its investigation, engineers found that certain servers became overwhelmed or stopped responding. Restarting those servers did not always solve the problem because some failed again after receiving new traffic.
Microsoft began redistributing connections, limiting traffic to affected infrastructure and applying configuration changes.
The company also investigated a recent network configuration change that coincided with the beginning of the disruption, although a definitive root cause had not been established in the reports reviewed.
Microsoft said it had no indication that the outage resulted from malicious activity or a cyberattack. Penn Mail Services+1

Which Microsoft Services Are Experiencing Problems?
The outage extends beyond Outlook. Several Microsoft applications depend on shared cloud infrastructure, which means problems affecting email services can interfere with other tools.
| Microsoft service | Reported impact |
|---|---|
| Outlook and Exchange Online | Mailbox access failures, connection errors and delayed email delivery |
| Microsoft Teams | Problems with calendar scheduling, meeting invitations and some Exchange-dependent functions |
| Microsoft 365 Copilot | Difficulty loading chats or accessing connected workplace information |
| Microsoft 365 Admin Center | Problems accessing certain administrative pages |
| Microsoft Planner | Reduced reliability when using tasks and plans |
| Microsoft Defender | Some security management and related features affected |
Microsoft’s incident information indicates that core Teams activities, including joining meetings and exchanging messages, generally remain available even when other features experience problems. OpenUptime
How Widespread Is the Outlook Outage in the United States?
The scale of the disruption became clear shortly after it began Thursday afternoon.

Users complained about being unable to open their inboxes, receive messages or send email.
The incident also disrupted organizations beyond individual households and offices.
In New York City, emergency management officials warned that residents might encounter delays when contacting city agencies by email or using online services connected to Microsoft systems. The city recommended alternative contact methods for urgent needs. ABC News
For American businesses, the disruption has created practical challenges involving customer inquiries, scheduling, employee communication and administrative tasks.
What Should You Do If Outlook Is Not Working?
The best response depends on whether Microsoft is experiencing a confirmed outage or your account is having a separate problem.
- Check the official outage status. If Microsoft has acknowledged an incident affecting Outlook or Exchange Online, local troubleshooting may not restore the service.
- Try another connection method. If the desktop application fails, you can try Outlook on the web. However, both methods may be affected by the same outage.
- Check your internet connection. Open another reliable website to determine whether your connection is working.
- Avoid repeatedly sending important messages. An email may be delayed rather than permanently lost. Multiple attempts can sometimes create duplicates.
- Contact your workplace IT team. Microsoft 365 administrators may have more specific information about problems affecting your organization.
- Use another approved communication method. For urgent work, a phone call or alternative company-approved messaging service may be more reliable.
Do not enter Microsoft account details on unfamiliar websites advertising emergency outage fixes.
If your organization’s Microsoft 365 environment is affected, avoid unnecessary account reconfiguration or software reinstallation until the service-health information indicates recovery.
Are Outlook Emails Being Lost During the Outage?
Microsoft has acknowledged delays in email processing but has not indicated that every delayed message is permanently lost.
During recovery, the company extended an email-processing timeout to 48 hours to help preserve delayed mail.
That measure is intended to give affected systems more time to process queued messages while engineers restore infrastructure capacity. It does not guarantee successful delivery of every individual message. The Verge
If an important email has not arrived, users should confirm delivery with the sender or their email administrator once the service stabilizes.
When Will Outlook Be Fully Restored?
Microsoft has not provided a firm deadline for complete recovery in the latest available reports reviewed for this article.
The company has reported progress in restoring server capacity and recovering mailbox access, but intermittent problems remain possible.
Users may also see different results depending on their region, Microsoft account type and the features they are trying to access.
As of Friday morning, Microsoft’s published incident information continued to classify affected Microsoft 365 services as degraded. OpenUptime+1
What Outlook Users Should Know Going Forward
The important point for Outlook users is that a connection error does not automatically indicate a problem with their device or account.
When Microsoft confirms a widespread outage, the most useful steps are to check service-health information, protect important communications and avoid making unnecessary account changes.
Microsoft is continuing its recovery work, but users should rely on official service updates before assuming the incident has been completely resolved.
For those still experiencing errors, checking the affected service’s status remains the fastest way to distinguish a widespread Microsoft problem from an isolated issue.
