Latest Message<\/th>\nTitle: Some users who are scheduling meetings may not receive accurate declined email messages in Exchange Online<\/p>\n

User impact: Users who are scheduling meetings may not receive accurate declined email messages in Exchange Online.<\/p>\n

More info: Specifically, when users send a meeting invitation that is declined by a resource room, the email response may be missing the Organizer’s details.<\/p>\n

While we’re focused on remediation, impacted users may be 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 Microsoft Teams. After adding attendees and selecting a time for the meeting, organizers with this feature available see a “Add room with Copilot” button which will enable Auto Room Booking. Once this is enabled, users will see “Copilot Managed” and “Copilot will rebook if the room declines or the meeting is 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.<\/p>\n

In order to enable this feature, users must have an active Copilot license and be scheduling meetings using the Outlook (new), Outlook on the web or Microsoft Teams.<\/p>\n

Current status: We’ve determined our fix deployment throughout our internal testing environment is roughly halfway complete, and our preliminary validations indicate the fix is successful in remediating impact. We’re aiming to begin deployment of the fix throughout the primary impacted environment by our next scheduled communications update.<\/p>\n

Scope of impact: Some users who are scheduling meetings that are being declined by a resource room may be impacted.<\/p>\n

Start time: Monday, October 27, 2025, at 12:00 AM UTC<\/p>\n

Root cause: A recent deployment implemented a design change that’s preventing the Organizers’ details from reflecting properly when a meeting invitation is declined by a resource room.<\/p>\n

Next update by: Tuesday, November 25, 2025, at 8:00 AM UTC<\/td>\n<\/tr>\n
