Why Outlook Spelling Check and AutoCorrect Options are Greyed Out and How To Fix It?


My Outlook 2010’s Spelling Check Options (called Proofing in Outlook 2010), as well as AutoCorrect Options were all greyed out, so I don’t get the usual correct as you type feature as I usually get on my other computers. Only the basic ones, like Always checks spelling before sending, are still available. What’s going on?

Turned out, that’s because I have a mixed Microsoft Office versions installed, running Outlook 2010 alone while Word is still on 2007. The features like Spelling Check and AutoCorrect in Outlook are integrated tightly with the same version of Word. So when Outlook couldn’t find a working copy of Word application, it greys out these features.

Each version of Office is installed in a number-based sub-directory under the main Microsoft Office folder. For example, my Office 2007 is installed in Office12 folder while my Outlook 2010 is installed in Office14 folder, both under Microsoft Office folder. When my Outlook 2010 launches, it looks for the Word executable file WinWord.exe in the same directory. If nothing found, it then disables all Word-depended features like Spelling Check.

So, based on this observation, the workaround to get around this issue was easy:

Copy the WINWORD.exe file from Office12 folder to Office14 folder, and restart Outlook.

The result? All previously greyed out Spelling Check and AutoCorrect Options features became available again.

A few final words

The workaround works well in a mixed installation of Office 2007 and Outlook 2010 but I haven’t tested in other combinations. It most likely will still work if the versions are not set too apart. Let us know what works for you.



  1. I do not have multiple versions of office so maybe someone else could try this: instead of copying the winword.exe file to the other directory, put a shortcut there and make sure it’s named winword.exe (nothing with “shortcut to”.
