Restricting booking of conference rooms
If you run the following command you will see that the default BookInPolicy is set to true, which means that everyone can use this resource.
Get-CalendarProcessing -Identity room-alias | fl *policy*
If you want to restrict access to this resource, set this to false.
Set-CalendarProcessing -Identity room-alias -AllBookInPolicy:$false
Then run the same command but exchange :$false with the mailbox user or the distribution group which should have access to the resource.
Set-CalendarProcessing -Identity room-alias -AllBookInPolicy <mailbox user/distribution group>
If you want to revert the changes made, run the following commands.
Set-CalendarProcessing -Identity room-alias -AllBookInPolicy:$true
Set CalendarProcessing -Identity room-alias -BookInPolicy:$none
