Once the languages have been selected in the Manage spellcheck languages, then the spellchecker will automatically use all the selected languages to spellcheck your email. It will give you suggestions in multiple languages.
Hi Damien
I am aware this is an old ticket, but the fact I am writing here also shows that there are still problems.
In my case, as other people have said, Outlook will only spellcheck for the top language.
Every time I write an email in another language, I need to open the settings and change the top language.
Since your solution appears to work for some users, is there something I can do to make Outlook "refresh" (or something) and it uses all 3 languages?
