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

More info: The problem impacted admins accessing the Service health section of the Microsoft 365 admin center. This impacted event communications listed under “Active issues Microsoft is working on”, “Issues for your organization to act on”, and “Issue history”. When admins clicked on events listed in any of these sections, the entirety of the communication wasn’t visible. For example, admins could see the Title and User impact of an event after clicking on it, but the Current status statement could be visually cut off. After clicking on an event, admins also saw a message indicating that “This message had formatting issues, which we are working to resolve.”

Final status: Deployment of the fix is complete and we’ve determined from service telemetry that this issue is resolved.

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 have been 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 caused communications to be truncated.

Next steps:
– We’re reviewing our validation and updating procedures to better detect and prevent issues like this prior to deployment in the future.

This is the final update for the event.
