Microsoft Teams is still recovering after an outage Monday afternoon. Microsoft says it’s attempting to bring the service back online after “a recent change to an authentication system” took some Microsoft 365 services down.
While a roll back to the change has taken longer than Microsoft expected, it’s now complete and Teams, Azure, and other Microsoft 365 services should be coming back online. However, in a 7:19PM ET tweet, the company said it is “taking steps to resolve some isolated residual impact for services that are still experiencing impact.”
Service health has improved across multiple Microsoft 365 services; however, we are taking steps to resolve some isolated residual impact for services that are still experiencing impact. Additional details can be found at https://t.co/Mg8Ss85kGk or under MO244568 if available.

The issues started around 3:30PM ET, and Microsoft quickly confirmed they were affecting users worldwide. This is the first major Microsoft Teams outage since the service went down back in September, alongside other Microsoft 365 services like Office 365 and Outlook. Microsoft also blamed its previous outage on a configuration change.
WarnerMedia even delayed the virtual premiere for Zack Snyder’s Justice League, due to Microsoft’s services outage today.
Microsoft now has 115 million people using its Microsoft Teams communications app every day. The service has grown rapidly during the pandemic, as students and businesses moved online for remote working and learning. As a result, a worldwide outage like this has now affected millions of people trying to use Microsoft Teams to communicate with co-workers, teachers, or fellow students.
