OneNote 365 host of issues

Question

I have a user experiencing several issues on a Win7 machine using Office 365 (local application).
Background:  She's created about 25 GB worth of OneNote folders and has been storing them on a company Sharepoint so others can edit them.  Every individual project is created as a separate Notebook.  They mostly just consist of project notes
and any emails associated with the project are exported into the Notebook.
Problem: A few weeks ago, she started having issues with OneNote saying that the cache needs to be deleted in order for OneNote to start.  Clearing the cache helped for a little while, but then after opening Notebooks again, more issues started coming
up.  When she goes to search using the search bar on the top right, if the result she clicks on is in another Notebook, nothing will happen.  If she minimizes the window, then brings it back up, then OneNote will finally switch Notebooks.  OneNote
has also been freezing (not responding) a lot recently.  About 2-4 times a day.  When she exits OneNote and tries to bring it back up, about 20% of her Notebooks are saying that they cannot sync changes and giving her the yellow triangle.
What I've tried:  I tried clearing the cache which helped a little.  I assumed OneNote was freezing and having issues because she had 200+ Notebooks open at a time and it was just too much.  Within minutes she started having issues though.
 I tried adjusting the backup schedule and reduced the number of backups to keep to 1 copy.  I then tried to delete the OneNote settings and optimize all the files.  Finally, I tried to use the built in Office repair tool which seemed to help
for about 3-4 hours before the same issues started coming up.
Any ideas?

Hi,
Please check if the user has exceeded the storage quota that’s been allocated to her.
Since the user is running into specific errors while using OneNote with notebooks shared on a SharePoint sites, we can also try the following thing:
Turn off Required Check-in/Check Out in the SharePoint Document Library
Do the following:
Navigate to the document library in SharePoint.
On the Library Tools ribbon, select Library >
Library Settings > Versioning Settings.
Set the Require Check Out option to No.
Turn off Minor Versions in the SharePoint Document Library
Do the following:
Navigate to the document library in SharePoint.
On the Library Tools ribbon, select Library >
Library Settings > Versioning Settings.
Set the Document Versioning History option to No Versioning.
Turn off Required Properties in the SharePoint Document Library
Do the following:
Navigate to the document library in SharePoint.
On the Library Tools ribbon, select Library >
Library Settings.
Under the table titled Columns, see if any items have a check mark under the
Required column.
Click any item marked as required and then set the Require that this column contains information option to
No.
