How to Edit a Word in the Spell Checker Custom Dictionary in Windows Mail

information   Information
The custom dictionary is the secondary dictionary for Windows Mail Spell Checker. It is the dictionary that you customize by adding your own words that you would like Spell Checker to also use while spell checking your message. This can be helpful if you misspelled a word you added to the custom dictionary from Spell Checker and you want to remove or edit the word. You may also want to add a word or add a whole list without having to do it one at a time in the normal way.
Note   Note
The custom dictionary file used by Windows Mail is located at this hidden system file location below. If you have changed the default location of the WinMail stores folder, then the UserDictionary.lex file will be located there instead.

C:\Users\(user-name)\AppData\Local\Microsoft\Windows Mail\UserDictionary.lex

Tip   Tip
Windows Mail only has the English (US), French (France), German (Germany), Spanish (International Sort) languages available in it. If you want or need a email program for languages other than these, then you might consider using the free Mozilla Thunderbird instead.

Thanks for the path for editing the Windows Mail "User" dictionary....

I could not use Notepad to open the user dictionary as the words came out as graphic symbols only. I started over using Wordpad and your editing steps then worked perfectly. Again, thanks for the steps to edit this list of user words.....
