Meeting Forward Notification - language?

Hello

I want to change the language of the "Meeting Forward Notification" mail to Danish.

Is it not possible to change that notification?

I have tried Set-Mailbox -Identity "Username" -Languages "Da-Dk" and the Set-MailboxRegionalConfiguration -Identity Username -Language da-DK -DateFormat "dd-MM-yyyy" -LocalizeDefaultFolderName:$true

But it doesn't help.

Any suggestions?
