An as yet unknown number of Microsoft customers globally are unable to access Microsoft 365 services including Teams, Exchange Online, Outlook, SharePoint Online, OneDrive for Business and Microsoft Graph, with Microsoft saying it has identified the problem as a network configuration issue.
Amid multiple reports on social media from people who are unable to access Teams, and a report from Downdetector that shows a leap in Microsoft Teams outages reported in the last 24 hours, a statement in Microsoft’s Admin Center said as of 9am GMT: “We’ve isolated the problem to a networking configuration issue, and we are analyzing the best mitigation strategy to address it without causing additional impact. We’ll provide more information once we have additional information.”
As far as the scope of the impact is concerned, Microsoft says: “Any user serviced by the affected infrastructure may be unable to access multiple Microsoft 365 services.”
While the problem was originally identified by the mainstream media as affecting India, we have been contacted directly on Twitter by people working within the legal technology sector in the UK who are affected. Data from Downdetector shows thousands of complaints from the UK alone.
