Incorrect availability rooms

Hi @Luc Aeby, 

Thank you for the update. I truly appreciate the time you took to review my answer and try the troubleshooting steps. I also sincerely apologize that the issue has not been resolved as expected. As you have already completed the basic troubleshooting steps and the issue still persists, it is reasonable to submit a support ticket to Microsoft Support. While I would love to resolve this directly, my current scope and resource limitations do not allow access to the internal systems needed for this type of troubleshooting. The best next step is to have your IT administrator submit a support ticket through the Microsoft 365 Admin Center. 

Once the ticket is created, a technical support engineer will be able to initiate a secure remote session, review backend configurations, run diagnostics, and escalate the case to specialized engineering teams if necessary. These teams are equipped to perform advanced troubleshooting and provide targeted solutions.

We hope the information provided helps point you in the right direction, and we are always here to assist as much as possible within our scope.

Hi @Luc Aeby, 

Thank you for reaching out and sharing your concern regarding how new Outlook shows room status when scheduling a meeting. I can totally understand how important is it for rooms status to be consistent. According your concern, I have tested the behavior in new Outlook and encountered same issue as yours. However, when tested again in Outlook on the web (OWA) the issue doesn’t occur on my test environment.   

To resolve the issue, I would recommend trying the following steps:  

1. Re-schedule the meeting using Outlook on the web  

• Go to outlook.office.com, go to Calendar > New event.  
• Re-schedule the meeting room.  
• Click Send.  

2. Contact IT admin  

If the issue persists after using Outlook on the web, I would recommend reaching out to your organizations IT admin and provide them with the following steps to verify how room processes calendar using PowerShell:  

Get-CalendarProcessing -Identity "<room_mailbox_email>"   

Key fields to look at:  

• AutomateProcessing  
• AllowConflicts  
• BookingWindowInDays  
• WorkingHoursStartTime / WorkingHoursEndTime / WorkingHoursTimeZone  

Incorrect working hours or mismatched time zone can cause Teams to interpret the room as unavailable while Outlook still shows it as free.  

If calendar processing settings are correct and the issue persists, your IT admin can also submit a support ticket to Microsoft Support.   

I hope this information is helpful. Please follow the steps above and let me know if it works for you. If not, we can continue working together to resolve the issue through the Microsoft 365 Admin Center.
