Microsoft Booking - double and triple bookings

Question

Hi, I work in IT and our users are complaining that they can double or triple book rooms. This is causing issues as multiple people turn up to the meetings where only one person booking should be allowed. I'm unable to find a solution for this. There is no any relevant option in Exchange Online - Resources - Meeting rooms or in Microsoft Admin centre - Settings - Org Settings - Bookings. Please see screenshots and advise a solution.

Hi @Mario Karp ,

Thanks for your reply!

Are you using an Microsoft 365 account?

If so, based on my research, i found an article which is similar as your issue:

It's suggested that you could refer to this article and try the solution:
Microsoft 365 users can reserve a meeting room even though it's already reserved for another meeting

Hope the above help!

The room resources default to block scheduling conflicts on creation. But this is only the case if the appointments are made by inviting the room when scheduling. If users can write directly to the room calendar (and they shouldn't), there's is no automatic scheduling processing and conflicts are allowed. You can check all the settings for a room with powershell, using

Get-CalendarProcessing roomname

This is the output from a newly created room with no changes:

You can also check the permissions:

Get-MailboxFolderPermission -Identity roomname:\Calendar

Usually this would be all that's needed, as no user has access to see event details or write to the calendar by default

Hi @Rafael da Rocha and @ChristyZhang-MSFT I just checked and allow conflicts is set to False. I also reapplied this permission with:
Set-CalendarProcessing -Identity roomemail -AllowConflicts $false Tried booking the room and it still allows multiple bookings. Could you please assist urgently? Regards, Mario

Users book the rooms in Teams or Outlook calendar and the rooms appear as Free even though they are already booked. Once user books the room there is confirmation email coming in about booking being successfull.
