Microsoft outage appears to be largely resolved (Teams, Outlook …)

A large-scale Microsoft outage where many users can’t access Outlook, Teams, Azure and more. The company says it is rolling back a network change it believes is responsible for the issue…

DownDetector started showing outages in the early hours of this morning, affecting a large number of Microsoft services:

  • Microsoft Teams
  • Exchange Online
  • Outlook
  • SharePoint Online
  • OneDrive for Business
  • Microsoft Graph
  • Power BI
  • Microsoft 365 admin portal
  • Microsoft Intune
  • Microsoft Defender for Cloud Apps, Identity and Endpoint

The company subsequently updated its Office 365 status page to reflect this.

Microsoft was initially unable to determine the cause of the outages, but later said it had “isolated the issue to network configuration issues.” It subsequently found out the cause.

We have rolled back a network change that we believe has an impact. We will monitor the service as the rollback takes effect.

BBC news reported that the Teams disconnection was particularly problematic.

Microsoft Teams is used by more than 280 million people globally, primarily in businesses and schools, where it can be critical for calls, meetings and general service organization.

According to Downdetector, problems have been reported in many countries around the world, with thousands of reports in India and Japan alone.

In addition to Teams and Outlook, the affected services, according to the Microsoft 365 status page, are SharePoint Online, OneDrive for Business, Microsoft Graph, PowerBi and the Microsoft 365 Admin Center.

The page states that “any user served by the affected infrastructure may be unable to access multiple Microsoft 365 services”.

As the BBC notes, it followed a bad day for the company, when it reported its slowest sales growth in six years. Just a week earlier, the company cut 10,000 jobs.
