Microsoft-365-Microsot-Apps

Microsoft 365 is suffering a major service outage that covers several larger Microsoft solutions. At the time of writing, the outage was ongoing until midday (GMT) and was causing access issues for SharePoint, Outlook, and Microsoft Teams.

According to Microsoft, the outage is covering Europe, the Middle East, and India. There were also reports in other parts of Asia but service has resumed in those regions from 9:33 GMT. However, in the other regions users had to wait longer until Microsoft resolved the issue on 12:26 GMT.

Microsoft provided initial confirmation of the Microsoft 365 outage at 7:05 GMT saying the outage is caused by a “network configuration issue.”

“Any user serviced by the affected infrastructure may be unable to access multiple Microsoft 365 services,” Microsoft said.  

The list of Microsoft 365 services affected is extensive: Exchange Online, Microsoft Teams, OneDrive for Business, SharePoint Online, Outlook, Power BI, Microsoft Graph, Intune, M365 Admin Portal, and several Microsoft Defender cloud components.

Incoming Fix

Essentially any solution you need to make Microsoft 365 useful as an enterprise cloud package is down. Microsoft provides the following information on the outage:

“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,” Microsoft said. 

“We’ve determined the network connectivity issue is occurring with devices across the Microsoft Wide Area Network (WAN). This impacts connectivity between clients on the internet to Azure, as well as connectivity between services in datacenters, as well as ExpressRoute connections. The issue is causing impact in waves, peaking approximately every 30 minutes. We are actively investigating and will share updates as soon as more is known.”

Despite this, at the time of writing the outage has been resolved, with Microsoft updating the M365 status on 12:26 GMT.
