If you found yourself working later in the day or a little past working hours yesterday, you may have run into a problem with your Office 365 services.

That’s because of a massive outage that affected several services, including Microsoft Teams, Outlook, Azure, Exchange, SharePoint, OneDrive Dynamics 365 and other applications.

Down Detector, a website that tracks internet outages, began posting about reports of outages around 5 p.m. ET. Users reported having problems logging and staying connected to severs.

Microsoft’s official 365 status Twitter first tweeted about the outage at 5:44 p.m. and at first identified a “recent change” that was believed to be the culprit.

“We’re rolling back the change to mitigate impact,” the company tweeted.

However, Microsoft didn’t see any improvement in successful connections after rolling back the change. At 7:48 p.m., Microsoft said it began rerouting traffic to alternate infrastructure while it investigated the root cause of the issue.
By 10:20 p.m., Microsoft said most users were back online aside from a subset of North American users. At midnight, Microsoft said all issues have been resolved.

In a statement given to CNN Business, a Microsoft spokesperson said there was “no indication that (the outage) is the result of malicious activity.”

According to Microsoft, a coding issue caused a portion of the company’s infrastructure to experience delays processing authentication requests, which resulted in users being unable to login into their Microsoft services.

Ever since the COVID-19 pandemic, Microsoft’s enterprise services have been extremely valuable as organizations continue to work remotely or adopt a hybrid work environment.

Any outages to services like Outlook, Teams, SharePoint and others affected this time can severely impact an organization as they need employees to connect with teammates from many different locations.
