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
Assistance will be deeply appreciated!
