With New-Mailbox​Export​Request, I can use something like "#Inbox#" to specify well-known folders regardless of the mailbox language. With get-mailboxfolder, get-mailboxfolderpermission and similar commands I cannot do that (or it is not properly documented). Instead I have to use workarounds to find out the actual name of the Inbox or Calendar first, which is not very convenient.

It would be great if all Exchange Commands dealing with mailbox folders would support language-independent references to standard folders.
