Outlook 2016 spellcheck option greyed out

After one of June's Win10's updates, some of our Outlook 2010 installations' Instant Search stopped working.

We were told to upgrade to Outlook 2016. Now the Outlook 2016 spell check is greyed out. (Options > Mail> Spelling and Autocorrect... > When correcting spelling in Outlook:  all options are greyed out).

We are running Windows 10 Pro, ver 1703 build 15063.674.

Office 2010 without Outlook

Outlook 2016

Assistance will be deeply appreciated!

Your Office version is 2010 and Outlook is 2016. For Spellcheck and Autocorrect, Outlook is dependent upon Word and it looks for WinWord.exe in the folder where it is installed.
1. Start Word and Outlook
2 Right click on Windows task bar and start Task Manager > Go to Processes tab > Right click on Outlook.exe and Open File Location
3, Do the same for WinWord.exe also and Open File Location
4. See whether they are in same location. If not. copy WinWord.exe in Outlook.exe folder and restart Outlook.

If the above doesn't work, let us know.
