If you’ve been trying to open Microsoft Outlook, send an important email, or access your Microsoft 365 account today, you may have encountered an unexpected problem.
You’re certainly not the only one.
A major Microsoft outage that began on Thursday, 12 November 2026, has disrupted Outlook and several Microsoft 365 services worldwide. What initially appeared to be an email connectivity problem soon affected businesses, professionals, and organisations relying on Microsoft’s cloud-based services.
Users have reported difficulty opening their inboxes, sending and receiving emails, accessing calendars, and using certain Microsoft Teams and Copilot features.
Microsoft has acknowledged the disruption and is working to restore normal service. However, recovery has been gradual, leaving many users wondering what actually happened and when Outlook will start working properly again.
What Happened to Microsoft Outlook?
The disruption began on 12 November 2026, with Microsoft recording an Exchange Online incident at approximately 9:47 PM IST.
Exchange Online is the cloud-based email service that powers business mailboxes across Microsoft 365. When its infrastructure experiences problems, users can lose access to their email regardless of whether they use Outlook on their computer, phone, or web browser.
As the incident developed, outage-tracking website Downdetector recorded nearly 130,000 reports of Outlook problems in the United States during the initial surge.
The issues were reported across multiple regions, including the United States, Europe, Australia, Japan, and India.
By Friday morning, 13 November, users in India were also reporting problems accessing their Microsoft accounts. According to Moneycontrol, Downdetector recorded 1,960 complaints in India at approximately 8:42 AM IST.
The disruption extended beyond Outlook, affecting several services that businesses use for communication and daily operations.
Why Is Microsoft Outlook Down Today?
Microsoft’s investigation has pointed toward problems within its cloud infrastructure, particularly the servers responsible for handling Exchange Online connections.
According to the company’s technical updates, some affected servers were experiencing unusually high loads and becoming unresponsive.
When those servers stopped processing requests, additional traffic was directed toward other available servers. This created further pressure on the remaining infrastructure and contributed to connectivity problems.
Microsoft has been working on several recovery measures, including restarting affected servers, redistributing traffic, repairing infrastructure, and making configuration adjustments.
Engineers have also investigated whether recent network configuration changes contributed to the disruption.
However, the company has not yet confirmed the final underlying cause.
Was the Outlook outage caused by a cyberattack?
With a disruption of this scale, concerns about a possible cyberattack are understandable.
However, Microsoft has stated that it has no indication of malicious activity causing the incident.
Based on the information currently available, the disruption appears to be related to infrastructure and service connectivity problems.
It is important to distinguish between a technical failure and a cybersecurity incident, particularly when the investigation is still underway.
Microsoft has indicated that it will provide a more detailed incident report once recovery is complete.
Which Microsoft Services Are Affected?
Although Outlook has received much of the attention, the outage has affected other parts of Microsoft 365.
Microsoft Outlook and Exchange Online
Users may experience problems opening their mailboxes, synchronising messages, and sending or receiving emails. Some emails may also be delayed.
Microsoft Teams
Certain functions connected to Exchange Online, including calendars and meeting scheduling, may not work properly. Core messaging and meetings may remain available for some users.
Microsoft 365 Copilot
Users may have difficulty accessing Copilot Chat, receiving responses, or retrieving information connected to their emails, calendars, and documents.
SharePoint and Other Microsoft 365 Services
Some features that depend on Exchange Online may experience errors. Microsoft has also reported problems affecting services such as Planner, Intune, and certain administration and security features.
Importantly, the outage does not mean that every Microsoft 365 feature is unavailable to every user. The impact varies depending on the service, region, and infrastructure involved.
Is Microsoft Outlook Working Now? Latest Status for 13 November 2026
As of approximately 3:25 PM IST on Friday, 13 November, Microsoft was seeing early signs of stabilisation across its affected infrastructure.
Some users and regions had experienced partial recovery, but the company had not confirmed that all services were operating normally.
Microsoft continued to repair affected systems and gradually reintroduce traffic while monitoring server stability.
The company also extended its email timeout window to 48 hours to help protect delayed messages during the recovery process.
There was no confirmed timeline for complete restoration in the latest update reviewed for this article.
If Outlook is still not working for you, the problem may therefore be connected to the wider Microsoft service disruption rather than your individual device or internet connection.
For the most recent information, check the official Microsoft service status page or the Microsoft 365 service health dashboard available to administrators.
What Should You Do If Outlook Is Not Working?
There are a few things worth checking before making changes to your email account.
1. Check Microsoft’s service status first
Before troubleshooting your computer or resetting your Outlook account, confirm whether Microsoft is experiencing an ongoing service disruption.
If Exchange Online is unavailable, reinstalling Outlook or repeatedly changing account settings is unlikely to solve the underlying problem.
2. Try another way to access your email
If you’re using the Outlook desktop application, try opening Outlook through your browser or mobile device.
This can help identify whether your particular application is having trouble. However, if the issue originates from Exchange Online, other versions of Outlook may also be affected.
3. Avoid repeatedly sending the same email
If an important email appears to be stuck or delayed, check your Sent Items and Outbox before trying again.
Repeated attempts could create duplicate messages once connectivity returns.
For urgent communication, consider calling the recipient or using another approved communication platform.
4. Inform your team or clients
If your business relies heavily on Outlook, let employees and important contacts know that email communication may be delayed.
A short message through another available channel can prevent unnecessary confusion, especially when customers are waiting for responses.
5. Wait for confirmed service recovery
When an outage originates from the service provider, there may be little an individual user can do to restore it.
Avoid unnecessary account changes unless there is evidence of a separate problem with your device or account.
Once Microsoft confirms recovery, check whether previously delayed messages have arrived and verify any important communications that may have been affected.
How Is the Microsoft 365 Outage Affecting Businesses?
For many companies, Outlook is much more than an application for sending emails.
It is connected to customer communication, internal approvals, meeting schedules, document sharing, and several other business processes.
Consider a company whose sales team uses Outlook to communicate with clients, whose accounts department receives payment confirmations by email, and whose employees schedule meetings through Microsoft Teams.
When these connected services experience disruptions, several routine activities can slow down at once.
Customer enquiries may go unanswered, important approvals may be delayed, and employees may find it difficult to coordinate their work.
The situation becomes even more challenging for organisations that depend on one communication platform for nearly everything.
This incident is a useful reminder that even established cloud services can experience unexpected failures.
Businesses cannot prevent every outage at a third-party provider, but they can prepare for the possibility.
Having alternative communication channels, clear internal procedures, and reliable recovery plans can help reduce disruption when important services become temporarily unavailable.
What Can Businesses Learn from This Outage?
The Microsoft Outlook outage raises an important question for organisations of every size: how prepared is your business when a critical technology service stops working?
A practical starting point is to identify which daily operations depend on external cloud platforms.
For example, if your company uses Microsoft 365 for email, a cloud ERP for inventory, and another platform for customer support, consider what would happen if one of those systems became temporarily inaccessible.
Would employees know whom to contact? Could urgent work continue through an alternative process? Would your team be able to recover or verify delayed transactions once the service was restored?
Businesses should regularly review their backup procedures, service dependencies, recovery arrangements, and communication plans.
Companies developing custom business software should also pay attention to system monitoring, application stability, controlled updates, and recovery testing.

Final Thoughts
The Microsoft Outlook outage of 12–13 November 2026 has affected users and businesses across multiple countries, showing how widely organisations depend on Microsoft’s cloud services.
Microsoft has reported progress in restoring affected systems, but full recovery had not been confirmed at the time of this update.
For users, the best approach is to monitor official service updates, avoid unnecessary troubleshooting, and use alternative communication channels where needed.
For businesses, the incident is an opportunity to review how critical systems are managed and what procedures are available when an essential service becomes unavailable.
