User impact: Users may have been unable to manage meeting times in Outlook on the web if they used a Japanese input keyboard.

Final status: We’ve confirmed that our fix to address the underlying code issue has fully saturated the affected environments and we’ve verified via telemetry that the impact has been remediated. Users still experiencing impact may need to empty the browser cache and reload Outlook on the web to allow the fix to take effect.

Scope of impact: The problem may have impacted any user who leveraged a Japanese input keyboard and was attempting to manage meeting times in Outlook on the web.

Root cause: A recent feature change, intended to fix another unrelated issue, introduced code regression that prevented users from managing meeting times in Outlook on the web if they were using a Japanese input keyboard.

Next steps:
– We’re reviewing our feature change procedures so we can better identify similar code issues during our testing and development cycles and avoid comparable impact in the future.

This is the final update for the event.
