Microsoft is investigating a networking issue after tens of thousands of users around the world have reported being unable to access services like Teams and Outlook.
In a series of tweets posted on the Microsoft 365 Status Twitter account, Microsoft said it was taking steps to isolate the problem, but did not mention how widespread it was.
"We're investigating issues impacting multiple Microsoft 365 services," said Microsoft, to which it later added: "We've rolled back a network change that we believe is causing impact. We're monitoring the service as the rollback takes effect."
Online outage tracker Downdetector shows almost 4,000 people in India have been impacted and more than 5,000 in the UK reported that Outlook was inaccessible. Australia, Japan, and the United Arab Emirates have also seen spikes in outage reports.
