Microsoft 365 Outage Hits Outlook, Teams And Copilot; Users Across India, US Report Email Access Issues
Microsoft 365 users across India, the United States and several other countries faced widespread service disruptions after a major Microsoft outage affected Outlook, Microsoft Teams and Copilot AI. The disruption, which began on Thursday, November 12, continued into Friday morning, November 13, leaving several users struggling to access their email accounts, send messages and use workplace applications.
The outage also affected other Microsoft 365 services, including Exchange Online and SharePoint Online. Thousands of users turned to Downdetector to report connectivity problems, raising concerns among businesses and professionals who depend on Microsoft’s cloud-based productivity tools for their daily operations.
Microsoft Outlook Down: Users Report Email Access Problems
Microsoft Outlook was among the most significantly affected services during the global disruption. Several users reported that their inboxes were not loading properly, while others experienced difficulties signing in, sending emails and receiving incoming messages.
According to Downdetector, reports of Outlook problems in the United States reached approximately 138,058 at the peak of the disruption. The number of complaints later declined, although users continued reporting difficulties.
In India, Outlook-related complaints also increased late Thursday night. Downdetector recorded approximately 2,157 reports at 11:42 PM IST on November 12. Reports increased again on Friday morning as employees attempted to access their workplace email accounts.
Some users reported problems with the Outlook application, while others experienced login failures and delayed email delivery.
Microsoft Teams And Copilot AI Also Face Disruptions
The Microsoft outage was not limited to email services. Microsoft Teams and Copilot AI were also affected, creating additional difficulties for people relying on Microsoft’s workplace ecosystem.
Users reported connectivity problems with certain Teams features, particularly those dependent on Outlook calendars and Exchange Online. Although messaging and online meetings were largely functional in several regions, some users experienced difficulties accessing calendar information and scheduling meetings.
Microsoft’s AI assistant, Copilot, also faced disruptions. Since Copilot integrates with Microsoft 365 applications to retrieve workplace information, problems with underlying services affected its ability to access emails, calendars and files.

The disruption also extended to third-party AI integrations. OpenAI and Anthropic reported issues with their Microsoft 365 connectors, affecting certain ChatGPT and Claude requests involving workplace emails, calendars and search functions.
What Caused The Microsoft 365 Outage?
Microsoft identified problems affecting its Exchange Online infrastructure, which supports email and calendar services for Microsoft 365 customers.
According to the company’s updates, several servers unexpectedly became unavailable, placing additional pressure on the remaining infrastructure. The resulting connectivity problems affected users attempting to access their Microsoft 365 accounts.
Microsoft engineers attempted multiple recovery measures, including restarting affected servers, adjusting network configurations and redirecting traffic to improve service availability.
However, the initial recovery attempts did not deliver consistent results. Some servers that became operational stopped responding again when they started receiving traffic.
The company continued exploring alternative solutions to restore server capacity and stabilise its services.
Microsoft also stated that there was no indication that the disruption resulted from a cyberattack or malicious activity.
Downdetector Outage Reports Reveal Global Impact
The Downdetector outage reports highlighted the international scale of the disruption. Users from the United States, India, the United Kingdom, Japan, Singapore and Australia reported problems accessing Microsoft’s services.
Reports indicated that the disruption extended across approximately 74 countries and territories.
In the US, Outlook-related complaints peaked at more than 130,000, while thousands of users also reported problems with Microsoft Teams and other Microsoft 365 applications.
These figures represent user-submitted complaints rather than the confirmed number of affected customers. Nevertheless, the sudden increase demonstrated how widely the disruption was being experienced.
Is Microsoft Outlook Working Again?
Microsoft began implementing recovery measures on Friday morning, with some users reporting improvements in service availability.
However, the restoration remained inconsistent in certain regions. Microsoft reported that some affected servers were responding positively after being restarted, but the company continued monitoring their performance and working on additional capacity improvements.
As of the latest updates available on Friday morning, November 13, Microsoft had not confirmed a complete and lasting restoration of all affected services.
Users experiencing problems were advised to monitor Microsoft’s service-status updates for further information.
What Should Users Do During The Microsoft Outage?
Users facing Outlook or Microsoft 365 connectivity problems can take a few basic steps while waiting for services to return to normal:
- Check Microsoft’s official service-status updates for information about affected applications.
- Avoid repeatedly refreshing Outlook if the service is experiencing server-side problems.
- Try accessing Outlook through its web version if the desktop application is not responding.
- Save important documents and unfinished work locally whenever possible.
- Inform colleagues about possible email delays and use alternative communication methods if necessary.
Conclusion
The Microsoft 365 outage has once again highlighted the dependence of businesses and professionals on cloud-based productivity platforms. With Microsoft Outlook, Teams and Copilot AI experiencing disruptions, users across India, the US and other countries faced difficulties managing their daily communication and work activities.
While Microsoft continued its recovery efforts, the inconsistent restoration of affected servers raised concerns about service reliability. Users will be watching for further updates as the company works towards restoring normal operations across its Microsoft 365 ecosystem.
