The fact that this isn't an option is insane to me. Not being able to turn this off makes the product effectively useless to me. I spend too much time correcting OneNote's overzealous and often wrong autocorrects.
Agreed. It wouldn't be such a big deal if it didn't "re-correct" things that I specifically went back and "un-corrected". I work in a field with a lot of acronyms, one of them being EHR. Currently, the only way to type that in OneNote is to type it, let
OneNote "fix" it, then go back over and fix it again. If I backspace to change it back, OneNote "corrects" it again as soon as I finish re-typing it.
In short, this problem with OneNote is forcing me to break a habit I've had for 20+ years that no other software requires me to break, simply because Microsoft won't add the ability to turn off auto-correct.
