Teams is back up and running after an outage took down multiple Azure and Microsoft 365 services.
Microsoft said the worldwide issue was caused by “a recent change to an authentication system”, adding that all users could be affected but not all had been.
Thank you for flagging this with us, the engineering team is aware and is working to resolve the issue. You can find additional updates on our status page: https://t.co/SQrPDQpBVb

Services including, but not limited to, Yammer, Outlook, Teams, Forms and SharePoint were impacted but most of these services have now been “recovered”, according to Microsoft 365’s status page.
The vendor kept users updated on Twitter, revealing it was in the process of rolling back the authentication update which took longer than expected.
We are currently rolling out a mitigation worldwide. Customers should begin seeing recovery at this time, and we anticipate full remediation within 60 minutes. Additional information can be found at https://t.co/AEUj8uAGXl or under MO244568 if available.
