Microsoft is currently probing an ongoing outage that has prevented customers from accessing and using the Microsoft Teams communication platform via web and desktop clients. While Microsoft initially acknowledged that the outage impacted the web app, customers have also reported difficulties accessing Teams via desktop clients on Linux and macOS.
According to Microsoft’s incident report, “The impact is specific to users who are served through the affected infrastructure and are not using a cached desktop build.” The company has noted that while they are focused on remediation, users who have access to a desktop build that is cached may not experience the impact.
Users affected by the outage have reported seeing “Operation failed with unexpected error” messages when opening the Teams website. Those experiencing issues with the desktop clients have seen messages such as “We could not connect to the internet. Try checking your connection” or “Error code – online_check_failed: retry attempts exceeded. Failed to connect to settings endpoint”.
Based on user reports, the outage appears to have affected Teams customers worldwide, with some users able to reach the login screen but unable to sign into their accounts. This incident follows closely on the heels of a seven-hour-long outage that took down Outlook’s web service for users across North and South America.
Microsoft reported signs of improved availability across multiple affected regions, including America, Asia-Pacific, Europe, the Middle East, and Africa. This improvement followed a reversal of a configuration change that had triggered the outage. Microsoft announced that the root cause of the outage had been addressed, and access to the Teams service was restored.
