Powershell: Get a list of members of Persistent Chat Room

To get information of specific Persistent Chat room, use following command
Get-CsPersistentChatRoom -Identity <Room Name>

Obviously, to get list of members of chat room, we will use following command
Get-CsPersistentChatRoom -Identity <Room Name> | select-object members

However, you will not get full list of members using above command.

To get full list of members of Persistent Chat, Use following PowerShell command

foreach ($member in (Get-CsPersistentChatRoom -Identity <Room Name> | Select-Object members).members) {$member}
