Spell Checker not working in Microsoft Word 2011 for Mac

The convenience of this macro is, once you know it works, all you need to do is open all documents requiring fixing, ALL AT ONCE, and run the macro one final time.

To force Australian English, change the language specification from wdEnglishUS to wdEnglishAUS

(in two places).

There is a Preference setting that, curiously, is saved with each document and is probably the root of your current problem: *Word > Preferences > Spelling and Grammar > Hide spelling errors in this document.*I've added it to the code as well, so here's a new version with the changes in boldface, which you can add manually:

Sub ApplyEnglishAUStoAllOpenDocuments()

For Each aDocument In Application.Documents

aDocument.Activate

'Apply language ----------------------

Selection.WholeStory

Selection.LanguageID = wdEnglishAUS

Selection.NoProofing = False

'Redefine the Normal style ----------------

ActiveDocument.Styles("Normal").LanguageID = wdEnglishAUS

ActiveDocument.Styles("Normal").NoProofing = False

'Enable spelling errors --------------

ActiveDocument.ShowSpellingErrors = True

'Save changes and close -------------

aDocument.Save

aDocument.Close

Next aDocument

End Sub

In case you don't know anything about macros, the name that follows the starting "Sub" is arbitrary (thus, you can use pretty much any descriptive name there, like Sub ChangeLang(), etc.) while comment lines start with an apostrophe and are ignored by Word.
