Microsoft said it’s investigating an authentication outage with Office 365, preventing users from accessing some of the company’s most widely used services, including Office.com, Outlook.com, and Teams.
The company’s status dashboard said the issue started at 2:25pm PT, and has impacted mostly consumer users across the globe for the last few hours. Some government users may also be impacted, the company said.
In a series of tweets, Microsoft said that it tried to fix the issue, but was forced to roll back its changes after the fix failed.
