Multiple Microsoft 365 services, including Outlook, Office 365 and Teams, experienced a massive outage last night, affecting millions of people around the world. The company said that it started investigating the issue after users started complaining that they were unable to log into their Microsoft 365 accounts. However, users who were already logged into an existing 365 session were apparently still able to keep using the service.
We’ve confirmed that the residual issue has been addressed and the incident has been resolved. Any users still experiencing impact should be mitigated shortly. Additional details can be found in the admin center under MO222965 or https://t.co/lbjX5iaxCX
Microsoft had earlier confirmed that its cloud services were facing an outage that affected millions of users across Office.com, Outlook.com, Teams, Power Platform and Dynamics365. “Starting at approximately 21:25 UTC, a subset of customers in the Azure Public and Azure Government cloud may encounter errors performing authentication operations for a number of Microsoft/Azure services, including access to the Azure Portals”, the company said.
