Microsoft Teams, Outlook, and other Microsoft 365 services are back online for thousands of users worldwide after a networking issue. The software maker intitially said it had “identified a potential networking issue” before rollling back a network change and monitoring its services to make sure they’re back online.

Thousands of users reported issues early this morning at around 2:30AM ET, with services like Microsoft Teams and Outlook email not loading for many across Europe and Asia. The outage lasted around four hours, with Microsoft listed the following Microsoft 365 services as affected:

  • Microsoft Teams
  • Exchange Online
  • Outlook
  • SharePoint Online
  • OneDrive for Business
  • Microsoft Graph

It’s rare to see multiple Microsoft services experience an outage simultaneously. Microsoft Teams was down for two hours in April 2021, after issues blocked connectivity for users across Europe and Asia.

While the Microsoft 365 Status account on Twitter provided updates for users, the Microsoft Teams account’s last tweet was from 12 hours ago, recommending that you “set your status to ‘Be right back’ and have a snack, friend.” That’s good advice for an outage so early in the morning, too.
