Some users who are scheduling meetings may not receive accurate declined email messages in Exchange Online
Service Restored

More info: Specifically, when users sent a meeting invitation that was declined by a resource room, the email response may have been missing the Organizer's details.
While the service provider were focused on remediation, impacted users may have been able to avoid impact by utilizing the Auto Room Booking feature, which would show up automatically if they have an active Copilot license when scheduling meetings through the new Outlook desktop client, Outlook on the web, or Teams. After adding attendees and selecting a time for the meeting, organizers with this feature available would see a "Add room with Copilot" button which would enable Auto Room Booking. Once this was enabled, users would see "Copilot Managed" and "Copilot will rebook if the room declines or the meeting was rescheduled". Additionally, when viewing the "Places finder", it should also show this feature as enabled, and when users click "Add a room or location", then "Browse all rooms", users will see "Rebook declined rooms" toggled on.

In order to enable this feature, users must have an active Copilot license and been scheduling meetings using the Outlook (new), Outlook on the web or Microsoft Teams.

Final status: The fix has fully saturated in the affected service environment, and after validating internally in our test environment, the service provider has confirmed that impact has been successfully remediated.
