Latest Message<\/th>\nTitle: Some users may be unable to access m365.cloud.microsoft<\/a> and receive an error <\/p>\n

User impact: Users may be unable to access m365.cloud.microsoft<\/a> and receive an error message. <\/p>\n

More info: Users received a “GetSections returned no conversation history” error message. <\/p>\n

Final status: Further analysis indicated that the previously referenced 400 and 503 error messages were unrelated to the issue described in this communication, and we’ve updated the communication accordingly. We reverted a recent service update that was intended to improve chat-loading functionality when accessing m365.cloud.microsoft and confirmed through service telemetry that the error rates have subsided and service is restored. <\/p>\n

Scope of impact: This issue may have affected some users attempting to access m365.cloud.microsoft<\/a>. <\/p>\n

Start time: Tuesday, September 8, 2026, at 4:30 AM UTC <\/p>\n

End time: Tuesday, September 8, 2026, at 5:15 PM UTC <\/p>\n

Root cause: A recent service update, intended to improve how chats are loaded when accessing m365.cloud.microsoft, rejected requests which resulted in m365.cloud.microsoft<\/a> failing to load. <\/p>\n

Next steps:
– We’re reviewing our testing processes to determine how we can identify similar issues prior to deployment so we can resolve these issues beforehand. <\/p>\n

This is the final update for the event.<\/td>\n<\/tr>\n
