Teams down: video conferencing appears to be back up following major Microsoft 365 outage

to update

Good morning – If you’re just logging in for work and having issues with Microsoft 365 – you’re not alone.

The platform is seeing widespread issues, with users across Europe and Asia unable to access a number of services, including Microsoft Teams and Outlook.

The good news is that Microsoft has apparently noticed the problem, so a fix may not be too far away.

“We are investigating issues affecting multiple Microsoft 365 services. More information can be found in the admin center under MO502273,” Microsoft 365 Status Account twitter He said (Opens in a new tab).

More info from Microsoft – it seems they found the cause of the problem, but haven’t fixed things yet.

As this tweet mentioned, users can find more information on the official Health Service Status page for Microsoft 365.

Doesn’t make for a particularly good read at the moment though…

The alert reads “Users may not be able to access multiple Microsoft 365 services,” indicating that the following services are affected:

  • Microsoft Teams
  • Exchange online
  • prospects
  • SharePoint Online
  • OneDrive for Business
  • Microsoft Graph

“We have identified a potential network issue and are reviewing telemetry to determine the next troubleshooting steps,” he adds, noting that any user served by the affected infrastructure may not be able to access multiple Microsoft 365 services.

For anyone still struggling with this problem, there may be good news soon.

Although there is no official confirmation, the Microsoft 365 Service Status page (Opens in a new tab) It no longer shows any problems, with a cheerful note that “everything is working fine”.

Reports of the outage are also rolling in on DownDetector after the massive spike earlier today – but until we get an official tweet from Microsoft, it might not be worth swaying too far…

Another update (Opens in a new tab) From Microsoft, which says it has now determined the cause of the problem.

“We have isolated the issue to a network configuration issue, and are analyzing the best mitigation strategy to address it without causing additional impact. We will provide more information once we have additional information.”

It adds that some users will still be unable to access services like Teams and Outlook, but it’s working on a fix.

Potential Further Progress – Microsoft 365 gremlin seems to have been identified…

Things have gone very quietly on Microsoft’s side, but DownDetector is still showing hundreds of complaints across Microsoft 365 as a whole, along with Teams and Outlook issues, so we’re guessing the fix hasn’t fully started yet.

On the health status page of the service (Opens in a new tab)Microsoft has expanded the list of affected services, with some new entries:

  • Microsoft Teams
  • Exchange online
  • prospects
  • SharePoint Online
  • OneDrive for Business
  • Microsoft Graph
  • powerpee
  • M365 management portal
  • Microsoft Intune
  • Microsoft Defender for Cloud Apps and Microsoft Defender for Identity

Microsoft now says that a fix for it has begun, with some previously affected users now able to access the tools they need.

“We have determined that a change in WAN routing caused an impact on the service. We have reversed the change and monitor the service as it recovers. Some customers who previously reported the impact have also reported recovery,” noted on the service health page .

Outage reports still fall on DownDetector (Opens in a new tab)However, some new complaints are emerging.

As the US goes online, problems may re-emerge, or even worsen – we’ve certainly seen it happen before.

Nothing concrete from Microsoft yet — last we hear, the company He said (Opens in a new tab) She was “continuing to monitor recovery.”

With users still complaining about outages in DownDetector, the fix may not be fully working yet…

Good news – Microsoft thinks the problem is finally recovering enough.

“We are monitoring telemetry which continues to show that the service is stable, and that the majority of users are able to successfully access the service,” she wrote in her latest update on the health service’s status page.

“We are continuing to monitor the service and take measures to confirm a full recovery.”

Well, it looks like the saga may finally be over.

The Microsoft Service Health Status page currently shows no problems, and although there is no official tweet, it now appears that everything is back to normal.

We’ll continue to monitor for any issues, outages, or other issues, but for now at least, the latest Microsoft Teams debacle may be at an end.
