Adding English(UK) as an additional Spell Checker in Windows Live Mail Version 2008


  • Windows Live Mail’s Version 2008 release does not include an option to choose an alternate UK English SpellCheck
  • The method below provides the ability to add the option for the UK English SpellCheck and also retain the US English SpellCheck
  • This method is ***not necessary or applicable*** for Windows Live Mail 2009



How to create English (UK) as an additional spellchecker in WLM

  • Compliments of Bob Lucas – posted in the Microsoft public newsgroup Windows.Live.Mail.Desktop


After a lot of trial and error, I have discovered a way of including the English (United Kingdom) spellchecker as an ADDITIONAL language option, without losing the default English (United States) spellchecker.

1. The Language ID for English (US) is 1033 (or 0409 in hexadecimal).

2. The language ID for English (UK) is 2057 (or 0809 in hexadecimal).

3. With Windows XP and later, set the folder options to “Show hidden files and folders”.

4. All additional spellcheckers are installed in a folder called “Proof” in “%userprofile%\Local Settings\Application Data\Microsoft\Windows Live Mail”, which includes a separate folder for each language.

  • The name of each different language folder is “prf00xx” or prf0xxx, where “xx” or “xxx” is the hexadecimal code for each language.

5. In “%userprofile%\Local Settings\Application Data\Microsoft\Windows Live Mail”, create a new folder named “prf0809” (hexadecimal for English (United Kingdom)) – and create a further sub-folder named “1”.

6. Then, open the folder “%programfiles%\Windows Live\ Mail\Proof\prf009\2”.

  • This folder contains the basic spellchecker files for various versions of the English language.
  • Copy the three files, mssp3en.lex; MSSpell3.DLL and spell.ini from “%programfiles%\Windows Live\ Mail\Proof\prf009\2” to “%userprofile%\Local Settings\Application Data\Microsoft\Windows Live Mail\prf0809\1” (i.e. one of the folders you created previously).

7. Then, right click on “spell,ini” (in “prf0809/1”) and change Lang=1033 to Lang=2057. Save “spell.ini”.

8.  Finally, open Windows Live Mail and click on Tools / Options / Spelling.

  • The updated list of installed spell checkers should include English (United Kingdom), in addition to English (United States). Set whichever version you prefer as the default spellchecker.
