Microsoft users across several countries are dealing with another frustrating day as a widespread outage affecting Outlook, Microsoft Teams and other Microsoft 365 services continues into Friday, November 13.
The disruption has affected everyday workplace activities, with users reporting difficulties accessing their email accounts, sending messages and using several cloud-based applications. Businesses and government organisations that depend on Microsoft’s productivity ecosystem have also experienced interruptions.
While Microsoft has reported some improvement in its recovery efforts, normal operations have not yet been fully restored for everyone.
The company is working on stabilising its affected infrastructure, although users are still waiting for a confirmed timeline for complete service restoration.
Microsoft Outlook and Teams Outage: What Happened?
The problem first emerged on Thursday, November 12, when users started experiencing difficulties accessing Microsoft Exchange Online, the cloud-based email infrastructure that powers Outlook for many organisations.
For several users, Outlook either failed to load their inboxes or became unreliable when sending and receiving emails. Some messages were also delayed, creating additional problems for people relying on email for their daily work.
The disruption was not limited to Outlook.
Several other Microsoft 365 services, including Teams, SharePoint Online, Microsoft Copilot and Microsoft Defender XDR, also experienced problems.
The incident quickly developed into a major service disruption, affecting users across multiple regions.
Microsoft Shares Progress on Its Latest Recovery Attempt
Microsoft has been working to bring its affected services back to normal, but its initial recovery attempts did not deliver the expected results.
In an update shared on its service health platform, the company reported encouraging signs of improved server stability after deploying a new patch across part of its infrastructure.
Engineers are monitoring the results and working to extend the fix to additional servers.
However, this does not mean the outage has been completely resolved. Microsoft has not provided a definitive restoration deadline, and some users may continue to experience connectivity issues.
The recovery process is particularly important because bringing affected servers back online is only part of the challenge. Microsoft also needs to ensure that its infrastructure can handle normal traffic without creating further disruptions.
Nearly 130,000 Outlook Outage Reports Recorded
The scale of the disruption became evident through reports submitted to Downdetector, a platform that tracks service interruptions based on user complaints.
Reports related to Microsoft Outlook reportedly reached approximately 130,000 at their peak in the United States on Thursday afternoon.
Microsoft 365 also accumulated nearly 300,000 outage reports on the tracking platform during the incident.
Although these figures represent user-submitted reports rather than a confirmed count of affected individuals, they highlight how widespread the disruption became.
Reports of problems continued appearing on Friday, indicating that the recovery process was still underway.
Which Microsoft Services Are Affected?
The outage has affected several applications within Microsoft’s productivity and cloud ecosystem.
Here’s a quick breakdown:
1. Microsoft Outlook
Users have experienced difficulties accessing their inboxes, sending emails and receiving messages. Delayed email delivery has also been reported.
2. Microsoft Teams
Some Teams-related functions have been affected, creating difficulties for people relying on the platform for workplace communication and collaboration.
3. SharePoint Online
The disruption has also affected Microsoft’s cloud-based collaboration platform, which organisations use to store, access and share documents.
4. Microsoft Copilot
The AI-powered assistant has experienced service-related issues, particularly with features that depend on Microsoft 365 work data.
5. Microsoft Defender XDR
Certain security-related functions connected to Microsoft’s broader enterprise ecosystem have also been impacted.
The extent of the disruption may differ depending on the service, region and infrastructure involved.
Microsoft Outage Also Creates Problems for Indian Users
The disruption has not remained limited to users in the United States and Europe. Indian users have also reported problems accessing Microsoft services.
According to reports published by The Economic Times, outage complaints from India began emerging late Thursday night and increased again on Friday morning.
The disruption has been particularly concerning for organisations that rely heavily on Outlook for customer communication and business operations.
Airline IndiGo also reported that problems with its email support channel could affect its ability to receive customer emails. However, other customer support channels remained available.
For employees, businesses and professionals who use Microsoft 365 throughout the working day, even a temporary interruption can create considerable inconvenience.
Is the Microsoft Outage Caused by a Cyberattack?
Naturally, a disruption affecting several widely used services raises questions about whether a security incident could be responsible.
However, Microsoft has indicated that it has no evidence of malicious activity behind the outage.
The company’s investigation has focused on problems within its infrastructure, particularly servers that became unexpectedly unavailable.
This placed additional pressure on the remaining operational infrastructure and contributed to connectivity problems.
Microsoft is continuing its investigation, and a detailed explanation of the underlying cause is expected through its post-incident reporting process.
At this stage, users should avoid assuming that the outage is related to a cyberattack.
Microsoft 365 Has Experienced Previous Outages Too
This is not the first time Microsoft users have encountered widespread service disruptions in recent months.
The company also experienced a Microsoft 365 outage in August 2026, when users reported problems signing in, connecting to services and sending or receiving emails.
That incident took several days to fully recover from disruptions associated with a software update.
The latest incident once again highlights how heavily businesses depend on cloud-based productivity platforms and how quickly infrastructure problems can affect everyday operations.
When Will Microsoft Outlook and Teams Be Fully Restored?
This is probably the biggest question for affected users.
Microsoft has reported improvements in server stability following its latest recovery measures. However, the company has not announced a confirmed deadline for complete restoration.
The situation remains dependent on the progress of infrastructure repairs, server recovery and the stabilisation of affected services.
Users experiencing problems should keep checking Microsoft’s official service updates rather than relying on unofficial claims about the outage being fixed.

Final Word
The ongoing Microsoft outage is another reminder of how dependent modern workplaces have become on cloud-based communication and productivity tools.
Outlook, Teams and other Microsoft 365 applications are part of everyday business operations, and even a temporary interruption can affect thousands of workflows.
Although Microsoft’s latest recovery efforts have shown encouraging signs, the company still has work to do before all affected services return to normal.
For now, users will have to wait for further updates as Microsoft continues working towards a complete resolution.
