Microsoft 365 is down! Microsoft 365 team said the issue was caused by expired authentication certificate, which prevented customers from using the service. Microsoft said it’s developing a fix to apply a new certificate to the service which will remediate impact.
DownDetector.com, an outage monitoring website, shows the outage started around 9:42AM Eastern Standard Time. The last stated there were 196 related problems reported in the last 24 hours.
“We’ve initiated the deployment of the updated certificate and are monitoring service health as the fix progresses. Additional information can be found under TM202916 in the admin center,” Microsoft said.
Microsoft 365 team made the announcement about two hours ago on Twitter.
We're investigating an issue where users may be unable to access Microsoft Teams. We're reviewing systems data to determine the cause of the issue. More information can be found in the Admin center under TM202916

Office 365 is a line of subscription services offered by Microsoft as part of the Microsoft Office product line. The brand encompasses plans that allow use of the Microsoft Office software suite over the life of the subscription, as well as cloud-based software as a service products for business environments, such as hosted Exchange Server, Skype for Business Server, and SharePoint, among others.
Facing growing competition from Google’s similar service Google Apps, Microsoft designed the Office 365 platform to “bring together” its existing online services (such as the Business Productivity Online Suite) into “an always-up-to-date cloud service” incorporating Exchange Server (for e-mail), SharePoint (for internal social networking, collaboration, and a public web site), and Lync (now Skype for Business) (for communication, VoIP, and conferencing).
There seems to a discrepancy between Microsoft Office team and what is currently reported on Portal.Office.com. Below is a screenshot of the site showing the Service Health. However, DownDetector maintains users are still having problems using Microsoft Office 365 services
