Mountain Lion Notes Crash When Using MS Exchange Notes

I was having the same issue! I finally found a solution to it!

1. Delete your exchange account from the Mail, Contacts & Calendars pane in System Preferences.

2. Go to Finder, click "Go" in the menu bar, click "Go to Folder" and type in "~/Library" (without the quotes) in the box. This will take you to your user Library folder.

3. Use the search box in the finder and type in "com.apple.notes" and click "Library" in the search bar that appears. This should now find several folders and files related to the Notes app. Rename or delete everything except the help files (with the lifesaver icons on them). Just to be safe, I'll list the files and folders you should delete or rename and their directory paths:

com.apple.Notes - /Users/danieloria/Library/Containers/com.apple.Notes/

com.apple.Notes - /Users/danieloria/Library/Containers

com.apple.Notes.plist - /Users/danieloria/Library/Containers/com.apple.Notes/Data/Library/Preferences

com.apple.Notes.savedState - /Users/danieloria/Library/Containers/com.apple.Notes/Data/Library/Saved

4. Restart your Mac. Put your exchange account back into System Preferences, you can go ahead and activate the Notes sync service.

5. Open Notes and it should be working now!

NOTE: I also deleted all the stored information related to the exchange account in Keychain Access when I deleted the 4 com.apple files. This may or may not be necessary, but I just thought it was worth mentioning.

This resolved it for me, thanks.

Note, I didn't delete my Exchange account, I just unchecked Notes in the Exchange account settings, followed the steps you provided, then turned it back on.

Thanks, this resolved my problem, as well. I deleted all of the items you mentioned, and when the exchange data was loaded it displayed folders i was able to see in outlook and now all of my notes are available.

thanks, again!

Worked for me too!

You're welcome everyone! Glad this helped some people!

I did exactly the same: uncheck the Exchange account to use Notes, and then everything worked again.

I could even reproduce it; when I checked the Exchange account to use Notes again, the Notes app started crashing immediately.

So for the moment I will not use the Exchange account with Notes ;-)

Thanks, Daniel O's post helped me too.

I could not get notes in ML to sync with my notes in Exchange. I turned off my iCloud and Exchange notes in the settings, deleted the files and folders noted above, emptied the trash, restarted my computer, then turn on Notes sync in iCloud and under Exchange again. Once it set up and synced, it all worked and now both accounts sync in real time.

Thanks Daniel.

Just recently ran into the problem with the notes app crashing on my MacBook. Daniel O, your solution worked. Thanks to all!!

I bookmarked this thread because yesterday my Exchange Notes on my MBA were not syncing. Performed the steps outlined above, and presto, it all worked again.

Solved my problem as well. You can simply rename the entire folder (~/Library/Containers/com.apple.Notes), reboot to clear it, and then re-setup the Exchange account. I have iCloud and two Exchange accounts syncing and one Exchange account was the problem child. Renamed the folder, deleted the offending account, restarted, re-added and away we go.

Thanks Daniel! 🙂

Thanks Daniel. You have solved my problem.
