I was able to fix the crash on startup by following these steps from another thread:

  • Delete this folder: ~/Library/Containers/com.microsoft.onenote.mac
  • Delete this folder: ~/Library/Group\ Containers/UBF8T346G9.Office
  • Open up “Keychain Access” app on your Mac, and search for “MicrosoftOffice”. If OneNote recognized that you signed in, you will have an entry with a long name. Delete it.
  • Restart your computer.
  • Try launching OneNote and signing in again.

    Deleting the folder UBF8T346G9.Office worked! I was able to sign back into my MS OFfice 360 account and no more crashes. Macbook Pro on el Capitan.

    Hi Ryan,

    Any help on this issue ???

    I haven't been able to use the One Note app on my work Mac or personal Mac for over 2 weeks.

    Neither app will even open without crashing.

    Thanks,

    Bart

    Having the same issue on my MacBook Pro.  Updated Microsoft Office Suite yesterday and now One Note won't open.  I even uninstalled Office, restarted my computer, and then downloaded Office again which I initiated from the Microsoft Office (365 Personal) website.

    Note, all other Office programs (Word, Excel, etc.) are working fine.  When I use the web version of One Note it works fine.  The One Note App on my MacBook Pro just won't work.

    The following is a link to the error message:
