Microsoft Office 365 services are coming back after major outage

Microsoft Office 365 services are coming back after major outage

Microsoft 365 was hit with a significant outage late Monday that affected users’ access to multiple services, including Outlook.

By late evening, services appeared to be largely restored: Microsoft tweeted at 9:21 p.m. ET that “most users should be experiencing relief.” The company added that it was “continuing to see significant improvement for affected services.”

Earlier, the company indicated affected services included,, Power Platform, Dynamics365, and Microsoft Teams including Teams Live Event.
According to Down Detector, a website that tracks internet outages, users reported issues with logging in, server connection, and Outlook. The downtime began around 5 pm ET for Office 365, according to the site.
Microsoft initially attributed the outage to a recent change to the platform, but later indicated it was “not observing an increase in successful connections after rolling back a recent change. We’re working to evaluate additional mitigation solutions while we investigate the root cause.”
Wait a moment, does that mean it could have been a massive, and somewhat audacious, distributed denial of service (DDoS) attack after all? Not according to a statement from a Microsoft spokesperson given to CNN Business: “we’ve seen no indication that this is the result of malicious activity.”
