Exchange Team released the newest version of the Exchange 2010 language pack and that it is available for download here.
This language pack resolves three key issues some customers have experienced;
- Events being logged in the application log for any user not using en-us as their chosen language after installing SP2 RU1.
- A wording error in the German version of OWA
- A wording error in the Dutch version of OWA
Note that Exchange 2010 Service Pack 2 included the full language pack, and if you are not experiencing the problems or have not installed any language packs post SP2 you do not need to apply this language
