your system has run out of application memory

Hopefully this is a way to reply to everyone? plz everyone let me know one way or the other. what I started doing is if i need to upload a large powerpoint file or something i go online and do it through the URL. So far this has mitigated the problem and I can highlight and write in the document on my iPad and I can usually view it without issues on my macbook. I have stopped trying to upload documents via the desktop application. Let me know if this is helpful or works for you guys!! microsoft sucks they need to fix this because i have way too many notes, charts, etc in onenote to try switching over.

Posting this in reply to a previous comment I posted on this thread.

I tried a number of options posted online including:

1. Making sure everything was up to date (One Note & IOS)
2. Closing opened Notebooks (This proved to be painful as to do this I was trying to cut and paste less-used sections from my one active Notebook into a new Notebook which I could then close. This meant the new Notebook was trying to Sync and boosting up the memory usage in the process, crashing the app and the computer etc.... I eventually succumbed to taking my computer offline and closing the workbook manually, risking losing the sections I was moving across to the new Notebook which hadn't finished syncing... I figured I had backups anyway. I don't think I actually lost much, most of it had managed to Sync to OneNote online).
3. Clearing Cache from the 'hidden' library files

But these didn't help.

Finally, I made sure I had my backups saved outside the application folders, then followed Microsofts steps to completely remove OneNote, reinstalled it, re-signed in, and so far the issue has been resolved.... I've been able to add PDF printouts to new pages and these have sync'd ok. There is a spike in memory usage when syncing up to about 5GB but it seems to come back down quickly... I'd suggest if you're having the same issue, try completely uninstalling OneNote - make sure you've moved your backup files out of the default location to somewhere else where you won't accidentally delete them in the uninstall!

Has this fix been permanent for you?

Hi there,

I am experiencing the same issue as many other people on this thread. I have accessed the activity monitor and regardless of closing the notebooks, I am still having 40+ GB being used while one note is open (even with one notebook open at the time).

Is there going to be any solution to this in the future? I have had to create an entirely new user on my MacBook to try to avoid this problem (apple's solution for me) , and then to once again encounter the same issue a week after creating the new user. So... It is clear that something is not working right.

I do not see the " com. Microsoft" in my library containers. So I was not able to try that solution.

I have 3 years of very important medical notes on OneNote. And literally the only reason I use a computer is for school. Please please help us all with this struggle.

Thank you,

Karma
