    Does this remove any data that was in OneNote prior to crashing?
    Or just “repair” the executable file?

    Yay a “fix” that actually worked… not my first rodeo on this :-)) OneNote was working perfectly well on my trusty MBP 2011 (after a few bumps) replaced it with a MBP 2016 – restored from Time Machine and …. OneNote didn’t work. Your fix DID Thanks so much

    This worked for me. Thank you so much! I purchased a new MacBook Pro and immediately the OneNote app crashed. This solved the problem.
