User impact: Admins may be unable to view full communications for events within the Service health dashboard of the admin center.

More info: The problem impacts admins accessing the Service health section of the Microsoft 365 admin center. This impacts event communications listed under “Active issues ‎Microsoft‎ is working on”, “Issues for your organization to act on”, and “Issue history”. When clicking on events listed in any of the aforementioned sections, the entirety of the communication isn’t visible. As an example, admins may be able to see the Title and User impact of an event after clicking on it, but the Current status statement may be visually cut off. Note that after clicking on an event, admins see a message indicating that “This message has formatting issues, which we’re currently working to resolve.”

Current status: We’ve investigated the issue and determined that a recent update to the Microsoft 365 admin center introduced a code regression that’s causing the problem. We’ve developed, tested, and started deploying a code fix to resolve the issue. Impact is expected to be remediated by our next scheduled update.

Scope of impact: Any admin attempting to view event communications in the “Active issues ‎Microsoft‎ is working on”, “Issues for your organization to act on”, and “Issue history” sections of Service health within the Microsoft 365 admin center may be impacted.

Root cause: A recent update to the Microsoft 365 admin center intended to improve Service health functionality by adding support for additional character inputs introduced a code regression that’s causing communications to be truncated.
