OneNote File Too Large, Sync Error: 0xE0000025
If you're seeing the 0xE0000025 error code, OneNote can't sync one or more large files because they're over the current size limit.
If you’re syncing to OneDrive, the limit for each file is 2GB. On SharePoint, this limit varies from server to server in your organization. If you don’t have permission to check your limit on SharePoint, talk to your server administrator to find out.
Removing files that are too large or reducing their size is only part of the solution. You may still need to take a couple more steps before the error message will go away.
In OneNote, click History > Notebook Recycle Bin > Empty Recycle Bin.
In OneNote, click History > Page Versions > Delete All Versions.

Step 1: Empty OneNote Recycle Bin
When you delete a page or a section from your notebook, it's moved to the Notebook Recycle Bin. This feature gives you a chance to recover data that's accidentally deleted. However, when large files stay in the Notebook Recycle Bin for too long, they can cause sync errors. You can resolve this by emptying the Notebook Recycle Bin.In OneNote, click History > Notebook Recycle Bin > Empty Recycle Bin.
Step 2: Delete All Pages Versions
OneNote stores cached versions of pages so you can go back to previous versions. If you deleted a large file (or several large files), it may still be in an older version of the page. You can resolve this by deleting your notebook history.In OneNote, click History > Page Versions > Delete All Versions.
