Microsoft 365 outage affects Teams and Outlook: what we know so far

Microsoft has confirmed that it is facing network configuration issues that are causing some Microsoft 365 services, including Outlook, Sharepoint, and Teams, to be unavailable to users in Europe, France, and other countries around the world.

On Downdetector, users from different regions are reporting that Outlook is not working. However, at 09:33 GMT, some users in Asia reported that services were resuming.

In an initial update at 09:00 GMT, Microsoft confirmed on its utility status dashboard that it found the cause to be a “network configuration issue.” “Any user served by the affected infrastructure may not be able to access multiple Microsoft 365 services,” Microsoft said in a statement.

“We have isolated the issue from a network configuration issue”

The affected services are Microsoft Teams, Exchange Online, Outlook, SharePoint Online, OneDrive for Business, Microsoft Graph, PowerBi, M365 admin portal, Microsoft Intune, Microsoft Defender for Cloud Apps, and Microsoft Defender for Identity.

“We have isolated the issue from the network configuration issue and are analyzing the best mitigation strategy to resolve it without causing additional impact. We will provide additional information as it becomes available,” Microsoft said.

The company warned earlier this morning that as of 07:05 UTC (0705 GMT), customers may experience network latency and/or timeout when trying to connect to Azure resources in Azure public regions, as well as Microsoft 365 and Power . BI.

Cancel Network Update

“We have determined that a network connectivity issue occurs with devices on the Microsoft Wide Area Network (WAN). This affects connectivity between clients on the Internet and Azure, and connectivity between services in datacenters, and ExpressRoute connections. The impact of the problem comes in waves, with peaks about every 30 minutes. We’re actively investigating and will share updates as we learn more.”

In a later update at 09:43:28 GMT, Microsoft stated that the issue was caused by a WAN update: “We have identified a recent WAN update as a likely root cause and we have taken steps to roll back that update. The latest telemetry shows signs of recovery across multiple regions and services, and we continue to actively monitor the situation.”

We have rolled back a network update that we believe is having an impact. We are monitoring the service until the cancellation takes effect.

Microsoft’s cloud shutdown comes after the release of Microsoft’s results for the second quarter of fiscal year 2023, where the company reported 2% or $52.7 billion in revenue growth thanks to cloud services. The personal computer division’s revenue fell 19% to $14.2 billion due to weak PC sales and shipments. Windows revenue from OEM PCs fell 39%.

This week, Microsoft invested $10 billion in OpenAI, the creator of ChatGPT, and laid off 10,000 people.
