"It is of outmost importance to us that the event turn into a breathtaking experience."
Microsoft Word is telling me that "turn" should be "turns," but I disagree. What say you?
It's one of those sentences where many native speakers would say 'It is of utmost importance to us that the event turns into a breathtaking experience', to the disgust of subjunctive-lovers.
Incidentally, I'd have 'the' before 'utmost'.
