Microsoft is investigating an ongoing outage blocking customers worldwide from accessing and using web apps and online services.
The list of affected services includes Microsoft 365 fort the web, the Microsoft 365 suite, Microsoft Teams, and Microsoft Planner.
"We're investigating access issues with Microsoft 365 Online apps and the Teams admin center. Further information can be found under OO544150 within the Microsoft 365 admin center," the company tweeted earlier today.
"Users may be intermittently unable to view or access web apps in Microsoft 365. We're reviewing service monitoring telemetry to isolate the root cause and develop a remediation plan," the admin center incident report says.
"New to Microsoft 365? This is your Microsoft 365 home page where you can see and access all of your apps. If it's empty, it could be that your user license was very recently assigned to you," the notification reads.
Another outage took down multiple Microsoft 365 services in January after a router IP address change caused packet forwarding issues between routers in Microsoft's Wide Area Network.
