Hi...try this script and copy paste it to notepad and save-as .PS1
But before that, run this command to enable booking restrictions.
Get-MailboxCalendarSettings "name of meeting room" -AllBookInPolicy $False
Then,you can now start adding users who can book this room by using the script below. Save it as AddUserPermissiontoMeetingRoom.PS1.
param([string]$user=$(Read-host "Type the name of the resource"),[string]$append=$(Read-host "User to append"))
$SnapInName = "Microsoft.Exchange.Management.PowerShell.Admin"
$testsnapin = $null
$testsnapin = get-pssnapin | where { $_.Name -eq $SnapInName}
if(-not $testsnapin){add-pssnapin -Name $SnapInName}
[array]$xDelegates = $append
$allreadyBooked = (Get-MailboxCalendarSettings $user).BookInPolicy
if ($allreadyBooked) {
$count = $allreadyBooked.count
Write-host "$count users set as BookInPolicy on $user"
foreach ($book in $allreadyBooked) {
$xDelegates += $book.DistinguishedName
Write-Host " "$book.DistinguishedName
}
}
Write-Host "Adding $append to $user"
Set-MailboxCalendarSettings $user -BookInPolicy $xDelegates
$allreadyCount= ((Get-MailboxCalendarSettings $user).BookInPolicy).count
Write-Host "$allreadyCount users set as BookInPolicy on $user"
Let me know if this Helps....
