Mixed versions of Word and Outlook
When you use mixed versions of Outlook and Word, ‘spell check on send’ should always work (if enabled).
For the spell check as you type and grammar checking features, you need to have the same version of Word and Outlook, often installed from the same suite. If you don’t have Outlook and Word installed from the same suite or are using mixed version, copy winword.exe into the same directory as outlook.exe. This enables spell check as you type and grammar features.
The version of winword.exe doesn’t make a difference, although really old versions of Word may not have the desired effect.
Make sure you copy, not move, winword.exe!
Look for your old and new Office installations at C:\Program Files\Microsoft Office, or if using 64-bit Windows, at C:\Program Files (x86)\Microsoft Office. Each installation will be in a subfolder called “OfficeXX”, where XX is the version number.
hmm. using this will likely drive me crazy in the future. not sure how Microsoft Updates and Service Packs will like having winword.exe in two locations. or how about next time I repair, upgrade or try to uninstall Office or Outlook? use this solution only as a last resort.
