Microsoft 365 Services Restored After Hours Long Global Outage
According to Microsoft, a coding issue caused a massive outage Monday night to services like Teams, Outlook, Exchange, SharePoint and others.
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.
Adown Detector, a website that tracks internet outages, began posting reports of outages around 5 p.m. ET. Users reported having problems logging in and staying connected to severs.
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 had been resolved.
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.
