Microsoft is investigating an outage that has left thousands of users around the world, including in Ireland, unable to access Teams and Outlook.
The tech giant thinks a network change could be why users are struggling to log on to its email and messaging services this morning.
Downdetector.com, which tracks outages, recorded thousands of people reporting problems with Teams, Outlook, Microsoft 365 and XBox Live.
The tech firm says it's "monitoring" the situation as they roll back a modification, they believe caused the glitch.
We've rolled back a network change that we believe is causing impact. We're monitoring the service as the rollback takes effect.
