Windows Mail can perform spellchecking, and it is possible to add new words to the dictionary used. If having added a misspelled word to the custom dictionary, then it can be removed like this:
- Open the following file in notepad:
- Find the word that have been spelled wrong and remove it. Make sure not to leave any blank lines.
- Save and close notepad.
The spell checker should now recognize the word as being misspelled again.
