Microsoft is investigating an outage that prevented thousands of users around the world from accessing the site’s services, including Teams and Outlook.
It didn’t say how many people were affected, but Downdetector.com, which tracks outages through a variety of sources including user reports, has logged thousands of people reporting issues with Teams, Outlook, Microsoft 365 and XBox Live.
It found that around 4,992 people reported problems with the UK’s Outlook email platform as of 8am – and 2,173 with Teams.
Users in areas such as Manchester, London, Birmingham, Norwich, Oxford, Brighton and Cardiff have reported problems.
The site has also reported over 3,900 cases of people reporting issues with Microsoft Teams in India and over 900 in Japan. Crash reports have also increased in other countries, including Australia and the United Arab Emirates.
During the outage, most users were unable to exchange messages, join conversations or use any Team features, forcing office workers back to face-to-face meetings and using other social media platforms to communicate with each other.
Microsoft tweeted: “We are investigating issues affecting multiple Microsoft 365 services. For more information, visit the admin center at MO502273.”
It later added: “We have identified a potential network issue and are reviewing telemetry to determine next troubleshooting steps.”
Azure, Microsoft’s cloud unit, also tweeted about the outage and said some users were having issues with the platform.

Many Microsoft users posted on social media to share updates, and the #MicrosoftTeams hashtag went viral on Twitter.
“Microsoft Teams and Outlook are having issues in Ethiopia… are these services down?” one social media user wrote on Twitter.
Another wrote: “Microsoft Outlook, Teams in Sri Lanka and around the world.”
Microsoft Teams is used by more than 280 million people worldwide and is an essential part of the daily business of businesses and schools that use the service to make calls, schedule meetings, and organize workflows.
Microsoft Exchange Online, SharePoint Online, and OneDrive for Business were also among the affected services, according to the company’s status page.
The outage comes after Microsoft – which employs more than 220,000 people, including 6,000 in the UK – announced plans last week 10,000 redundancies throughout its global operations.
In a memo to employees, chief executive Satya Nadella said the layoffs, which affect less than 5% of the workforce, were the result of a fall in investment amid concerns that the US and other key growth markets were heading into recession.
