Spell Check in Outlook 2010 not working?

Posted: Tuesday, October 19th, 2010 by Ted

We recently ran across an issue with one of our customers who upgraded only Outlook to 2010 while keeping the rest of Office at 2007. They called in stating that Outlook’s spell checker wasn’t working anymore so Kevin found the fix:

When users upgrade just Outlook, not the whole Office Suite, it doesn’t know where to look for Word as its editor, since it is also looking for Word 2010. This means the auto correct features won’t work. Here is the fix:

All you have to do is copy winword.exe to the office14 folder.


Copy Winword.exe from here C:\Program Files\Microsoft Office\Office12\


C:\Program Files\Microsoft Office\Office14

Make sure that you copy, not move the file or there could be other issues that you’ll run across but this will do the trick!

    I have Word 2010 and Outlook 2010. This did not help me. I get the automatic spelling/grammar checking AND automatic carriage returns when I am REPLYING to an email. If I am generating a brand new email, the spelling/grammar checking/auto carriage return goes manual. Very frustrating.

    Thanks – this is great. it also works the other way around – if you have outlook 2007 and word 2010 then just copy winword.exe from office14 to office12.

    We have just upgraded our Office suite from 2003 to 2010 with the exception of Outlook (due to an add in incompatibility). I have tried to copy the new WinWord.exe from 2010 (office 14 folder) to the Office 11 folder and this allows me to select Word as the email editor which is didn’t before. Only problem is when it tries to open a new email it errors because Word 2003 isn’t installed. Any ideas?

    Thanks for great solution! I have MS Home & Student 2007 and Outlook 2010. It was very annoying that Outlook wouldn’t spell check as I typed. Your fix corrected the spelling. – Thanks

    This solution does not seem to work for 2003 Word with 2010 Outlook. I copied the winword.exe file from C:\Program Files (x86)\Office2003\OFFICE11 to C:\Program Files\Microsoft Office\Office14; closed and reopened Outlook and still no synonyms show up when writing e-mails (“no suggestions” and “Thesaurus” are greyed out). Using Windows 7 Professional Edition.

    Did I do the process correctly? Any suggestions would be appreciated! Thanks.
