Microsoft users were left without access to a number of services for several hours because of an outage.

The online suite of Microsoft 365 services, including the messaging and conferencing app Teams, was affected for several hours on Monday evening thanks to an issue caused by “a recent change to an authentication system”, according to the technology giant.
