Dear All,

We are using office 365 and exchange online and use outlook for users to book meeting room, by sending email to the specified room number. Normally user just need to initiate a new meeting, then find the room, send out the meeting appointment, then user will receive an email saying the booking is accepted or rejected (if conflict).

This works for most of our meeting rooms, however we have a few meeting rooms behaved differently. There was no email replied to the user, and the status remains tentative (which means the room was not accepted or rejected). We've checked on the settings from exchange online, but didn't see any obvious differences. Any idea what areas we can look into and locate the root cause?

Any idea would be really helpful! Thanks a lot!

    Hi @Zhengqi Lou-MSFT ,

    Thanks a lot all the same for your help. It's something I've learned from you:)

    However, we've found out the root cause was about the exchange setting, after I enabled the "Automatic processing" option via Exchange - Resource, it worked out now:0

    Thanks again for all your efforts, it's really appreciated:)

    Hi @EavenHuang-0590 ,

    Good day!

    Could you see these rooms in your Room Finder? And can you book them on OWA?

    You could try enable the external request with:

    Set-CalendarProcessing "<Room Name>" -ProcessExternalMeetingMessages $True  
    

    And also, you could compare the properties of these rooms and the normal rooms using this cmdlet:

    Get-CalendarProcessing "7F-1" | FL  
    

    Here is an article that may help: Resources in Exchange don't respond to meeting requests

    Best regards,
    Lou
