Postbox translation in CRM 4.0

Hi folks,

all adresses that are listed in my application contains the german word 'Postfach' instead of the Norwegain word 'Postboks' (logon language).

How can I check/find if a translation was maintained for this word in SE63? There I can´t find the specific table/word.

Maybe somebody can help me?

thanks & regards,

André
