Microsoft has confirmed that some of the Microsoft 365 services are currently down again. The company confirmed this via its official Microsoft 365 Status X handle as it notes that the Microsoft 365 Admin Center may be down. The tech giant has informed that you can get status updates regarding the progress of the bug under the issue ID "MO1281730". This is rather ironic considering the admin panel itself is not accessible due to the bug and that's where typically bugs and outages are tracked.

We're investigating an issue with accessing some web-based Microsoft 365 services when using the latest version of Google Chrome. We're currently taking action to address the problem. More details can be found in https://t.co/uSHwRmXFJZ or under MO1281730 in the admin center.
