Some Microsoft services, including Outlook, Office 365, and Microsoft Teams, experienced a multi-hour outage on Monday, but they should be back for most users, according to the company.
“We have confirmed via our monitoring that the majority of services have recovered for most customers,” reads a notice on Microsoft’s Office status page. “However, we continue to see a small subset of customers whose tenants are located in North America region who are still impacted. We’re now investigating mitigation steps for those customers who are still affected.”
