If you're waiting for an important email today that never arrived, it may not be the sender's fault. Microsoft is experiencing a widespread outage of its online services. Users are reporting that they can't open their Outlook inbox, send or receive messages, and the issues are also affecting Microsoft Teams, Copilot, and the broader Microsoft 365 ecosystem.<\/p>\n\n\n\n
The problems began on Thursday, November 12, 2026, primarily in the United States. According to the Downdetector website, the number of reports of problems with Outlook reached almost 130,000 shortly after 7 p.m. Slovenian time. This does not mean that exactly that many users were affected, as Downdetector collects reports and does not measure the actual number of inactive accounts.<\/p>\n\n\n\n
Microsoft has officially acknowledged the outage and is investigating the issues preventing users from accessing their Exchange Online mailboxes. While initial reports focused on North and South America, the company later warned that the disruption could impact connectivity to Microsoft 365 services in other regions as well.<\/p>\n\n\n\n
Outlook users are experiencing the most problems. Some are unable to open their mailbox at all, others encounter errors when sending and receiving messages, or the contents of their mailbox take an unusually long time to load.<\/p>\n\n\n\n
The issue is not necessarily limited to Outlook on the web. Microsoft has confirmed that multiple ways to connect to Exchange Online servers may be affected, including Web Access, MAPI, Exchange ActiveSync, and REST APIs. This means that issues may also occur in desktop and mobile applications, not just in a web browser.<\/p>\n\n\n\n
User reports also indicate disruptions to Microsoft Teams and Copilot. These are not necessarily as extensive as Outlook, but they further demonstrate how interconnected the individual services are in Microsoft's cloud environment.<\/p>\n\n\n\n
It was initially unclear why users suddenly lost access to their services. Microsoft later discovered that part of its infrastructure in several regions was experiencing unusually high load.<\/p>\n\n\n\n
Upon further analysis, the company discovered that some servers unexpectedly became unavailable, forcing the remaining servers to take on more requests, which may have contributed to the connection failures.<\/p>\n\n\n\n
Engineers have begun rerouting traffic to other parts of the infrastructure, restarting affected servers and implementing load-reduction measures. Microsoft has also temporarily paused the rollout of changes to the affected environment, according to Reuters.<\/p>\n\n\n\n
Such incidents highlight one of the less pleasant aspects of cloud services. A user can have a perfectly working computer, a reliable internet connection, and a properly configured application, but still be unable to access their data. If the provider's infrastructure fails, local troubleshooting usually doesn't help.<\/p>\n\n\n\n
Microsoft has described the earlier Teams outage in North America as resolved, but that does not mean the broader issue with Outlook and Exchange Online has been resolved. As of Thursday evening, the number of reported cases had begun to decline, but some users were still experiencing issues. Microsoft continued to remediate its infrastructure, and full restoration of all affected services had not been confirmed at the time of writing.<\/p>\n\n\n\n
It has not yet been confirmed that the outage was the result of a cyberattack or a breach of user accounts. Available information points primarily to infrastructure and connectivity issues.<\/p>\n\n\n\n
If you are having problems with Outlook, first check to see if your internet connection is working normally. You can also try the web version of Outlook, but due to the nature of the outage, there is no guarantee that it will work better than the desktop application. Reinstalling Outlook, changing your password, or deleting your user profile will likely not resolve the issue in this case. In the event of a major outage of the server infrastructure, it is usually best to wait for service to be restored.<\/p>","protected":false},"excerpt":{"rendered":"
