Microsoft Teams is currently down worldwide. Microsoft says it is trying to bring the service back online after “a recent change to an authentication system” brought down some Microsoft 365 services. “We are reversing the update to mitigate the impact,” says Microsoft 365 status account, but the rollback is “taking longer than expected”.
The problems started around 3:30 pm ET, and Microsoft quickly confirmed that they are affecting users around the world. This is the first major Microsoft Teams outage since the service crashed in September, along with other Microsoft 365 services, such as Office 365 and Outlook. Microsoft also attributed the previous outage to a configuration change.
Azure Active Directory also appears to be having problems as part of this outage, and Microsoft’s Xbox prepaid codes are also not working at the moment.
The process of reverting the change is taking longer than expected. We will provide an ETA as soon as one becomes available. Additional information can be found at https://t.co/AEUj8uAGXl or at MO244568, if available.
