A worldwide Microsoft Teams outage is blocking users from logging into their accounts, and preventing those already logged in from sending and receiving messages.

Microsoft is currently monitoring telemetry and investigating to identify the issues causing degraded chat functionality.

The Microsoft 365 Service health status page is currently directing customers to the Microsoft 365 Status Twitter account for more details regarding this widespread incident.

"We’ve confirmed that this issue affects users globally," Microsoft said on Twitter. "We’re reviewing monitoring telemetry and recent changes to isolate the source of the issue."

"In parallel, we're reviewing recent changes made to the service as a potential root cause," according to additional info posted under TM252802 in the Microsoft 365 admin center.

Initial evidence suggests that any Teams user could be affected by these ongoing issues.

"Users able to access Microsoft Teams may experience degraded performance with multiple features," Microsoft added.

I assumed some sort of DDOS attack until this bit - "In parallel, we're reviewing recent changes made to the service as a potential root cause,". A bit of 'egg on their face' by causing this themselves might be better than an external attack affecting service worldwide.
