Microsoft Teams, Outlook, Xbox and other Microsoft 365 services all experienced varying degrees of outage and delay this afternoon, mainly affecting users in Asia and Europe.
Microsoft said it had "identified a potential network issue" and was troubleshooting a fix to bring services back online.
A number of users on China's Twitter-like Weibo also reported that major office apps such as Outlook and Teams were unavailable.
As of this post, Microsoft said it has rolled back the network changes that affected it. If you are experiencing problems, you can wait for a while. Expect to see the network improve after the rollback takes effect.
