(Reuters) – Microsoft Corp said on Wednesday it was investigating a networking problem that affected multiple services, including Teams and Outlook, with outage reports saying the platforms were down for thousands of users around the world.
Microsoft (NASDAQ: ) did not disclose the number of users affected by the outage, but data from the outage-tracking website Downdetector showed more than 3,900 incidents in India and more than 900 in Japan. Reports of outages also increased in Australia, Britain and the United Arab Emirates.
Downdetector tracks outages by comparing status reports from sources, including errors submitted by users on its platform.
“We have identified a potential networking issue and are reviewing telemetry to determine next steps to resolve the issue,” Microsoft said in a tweet.
During the outage, most users were unable to exchange messages, join calls, or use any feature of the Teams app. Many users took to Twitter to share updates on the service outage, with #MicrosoftTeams trending as a hashtag on the social media site.
Microsoft Teams, used by more than 280 million people worldwide, is an integral part of daily operations for businesses and schools, which use the service to make calls, schedule meetings and organize workflows.
Other affected services included Microsoft Exchange Online, SharePoint Online, OneDrive for Business, according to the company’s status page.
