How to fix OneNote for Mac crashes on startup


When using OneNote for Mac version, MacBook Pro crashed. After rebooting MacBookPro, it reported Microsoft OneNote had caused the crash. Then every time when i open OneNote, app crashed immediately.

Reinstalling OneNote Mac app via Appstore or clearing caches, does not fix the issue. OneNote keeps crashing on start.

Solution:-

1. Delete the following folders on your Mac.

~/Library/Containers/com.microsoft.onenote.mac

~/Library/Group/Containers/UBF8T346G9.Office

2. On your Mac OS X, open “Keychain Access” app and search for “MicrosoftOffice”. If OneNote app recognized that you signed in, you’ll have entry with long name. Delete it.

3. Restart your Mac computer.

4. Then try to launch OneNote app and signing in again.

That solution won't work for me. I run OneNote on my MacBook pro, and OneNote keeps crashing every 70 seconds.

I've searched for those folders ~/Library/Containers/com.microsoft.onenote.mac and
~/Library/Group/Containers/UBF8T346G9.Office, and neither one exist on my computer.

so what do I do now?

Restart the Mac.

Open OneNote on a PC configured to sync to the same account, and wait for the PC to fully sync.

Open OneNote on the Mac, and don't do anything until syncing is complete.

This worked for me! I have a 13" MBP retina 2015

I found the 2 files and deleted them, although I didn't find the keychain log in your step #2… After I deleted the files I didn't even have to restart – i just re-opened my office apps and signed in again = presto

Thanks a million.

To access the "Containers" folder, first go into the desktop and open Finder. Click "Go" in the menu up top. Once the drop-down menu opens, hold down the "Option/alt" key. A hidden Library folder will now be available. Click on that menu and you will be able to access the hidden containers folder.

Oh man, lifesaver, couldn't get the app to do anything.
Worked like a charm. Bookmarked for future reference.
Thanks so much
