I have been strugling with a “Set-CalendarProcessing” cmdlet to be able to restrict booking of meeting room using the -BookInPolicy setting.

After some (ALOT) of testing it`s clear that this setting only supports regular “Distribution groups” and therefore i cannot use the already created dynamic group created.

I therefore created this little script for copy-ing members from the Dynamic group over to the regular group!

### Copy members from dynamic distribution group to regular group"

$users = Get-DynamicDistributionGroupMember -Identity "xAuto Meetingroom bookers"

foreach ($user in $users) {
    Add-DistributionGroupMember -Identity "xManual Meetingroom bookers" -member $user.PrimarySmtpAddress
}
