Setting mailbox Folder Permissions in Any Language

I have found rather often that I need to set the permissions  on a mailbox, but the language may not be in English.  This is especially true for Calendars.  I used this script when setting up Polycom Real Connect.  You would want to change the filter and the user attributes

a few things, you may want to user a better filter for the displayname for just your conference rooms, you could do a filter on roomtype

$calendars = get-mailbox -Filter {(RecipientTypeDetails  -eq "RoomMailbox")} | Get-MailboxFolderStatistics -FolderScope calendar; $calendars | %{Add-MailboxFolderPermission $($_.Identity.Split("\")[0] +":\" + $_.Identity.Split("\")[1]) -user UPNofUser -AccessRights Reviewer}

Now you may have forgotten the account you want to use for the UPNofUser, you can do that by just getting the information of an existing mailbox.

Get-MailboxFolderPermission "RoomIdentity:\calendar" | fl
