Is the Microsoft 365 Web Portal Experiencing a Regional Login Outage?
Asked by

Is anyone else having trouble signing in to the Microsoft 365 web portal at https://m365.cloud.microsoft? Several users are receiving a "something went wrong" error. Direct access to Outlook, Teams, and OneDrive still works, so the problem appears limited to the main portal. There's also a noticeable spike in outage reports. Are others seeing the same behavior, and does it seem limited to certain regions or tenants?
Answers
Yes, it’s failing for several users in the United States, including the Northeast and eastern regions. The portal login is affected, while the individual services appear to be working.

It isn’t universal. Some users in the western and central US, the UK, and parts of the Netherlands can still access the portal normally. This looks like a regional or tenant-specific issue rather than a complete outage.

We’re seeing this in Europe too. One of our tenants gives a sign-in error, while two others load very slowly and sometimes trigger repeated validation or MFA prompts. It may be affecting tenants unevenly.

Our support desk is getting reports from a subset of users, even though access works normally for others. For troubleshooting, it’s worth checking whether the failure is simply loading the portal or whether authentication fails after the page opens.

We’re also seeing intermittent problems installing Office while provisioning laptops through Intune. That could be a separate CDN or deployment issue, but it may be worth checking the service health dashboard for related incidents.
