We're investigating reports of users experiencing issues accessing Exchange Online mailboxes through multiple connection methods in the Americas. More details can be found in the Microsoft 365 admin center under EX1550543.
We're testing a configuration change to address a problem that's causing servers to fail automated health checks and become unavailable. In parallel, we've initiated a restart of all affected servers and are monitoring health as they return to service. More info under EX1550543 and MO1550821 in the Microsoft 365 admin center, as well as status.cloud.microsoft if the admin center is not available to you.
We've not identified any recent change correlated with the start of impact; however, our investigation indicates the failed health checks may originate from a specific component that's responsible for processing server health. We've taken steps to prevent additional servers from being impacted while we work to return the affected servers to service.
