Hi @Mike Weldon, 

Welcome to Microsoft Q&A forum. 

Thank you for reaching out and sharing your experience and the error code. I can totally understand the inconvenience this issue may have caused. According your concern, the issue could be due to the SharePoint document library settings and its Information Rights Management settings.  

To resolve the issue, I would recommend trying these steps: 

1. Clear OneNote cache again 

I understand you already cleared the cache, but the issue came back afterward. So please try clearing the cache again using the steps below: 

• Back up notes: 
  • Choose File > Options. 
  • In the OneNote Options dialog box, choose Save & Backup. 
  • On the right, under Save, choose Back Up All Notebooks Now. 

• When you see the notice that the backup is successfully completed, select OK. 
• Close OneNote Desktop App. 
• Open the following file location: C:\Users<user>\AppData\Local\Microsoft\OneNote\16.0 

• You will see a folder named cache. Right-click and delete it. 
• Re-open OneNote Desktop App and let it sync. 

2. Turn off Required Check-in/Check-out in the SharePoint Document Library 

• 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. 

3. Turn off Versions in the SharePoint Document Library 

• Navigate to the document library in SharePoint. 
• On the Library Tools ribbon, select Library > Library Settings > Versioning Settings. 
• Set the Document Version History option to No Versioning. 

4. Turn off Required Properties in the SharePoint Document Library 

• Navigate to the document library in SharePoint. 
• In 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.  

5. Update IRM settings 

IRM in SharePoint is designed to control and protect files downloaded from a library by applying restricted permissions on download. This can cause a notebook hosted on an IRM protected SharePoint document library and that OneNote fails to upload a newly created section because upload is denied with the user’s credentials, resulting in persistent sync error. To move forward, please contact your SharePoint administrator check whether the library is IRM protected by taking these steps: 

• Open the SharePoint document library that contains the notebook. 
• Click on gear icon all the way to upper right corner of the document library shown in the browser to open side pane, select "library settings"  
• Click "More library settings" in the side pane  
• If you see "Information Rights Management" that means you can view the setting. Select to view the setting  
• In the Information Rights Management (IRM) setting view, if you see "Restrict permissions on this library on download" checkbox checked, then that means IRM protection IS enabled for the document library.  

If IRM is enabled, please work with your SharePoint administrator because this is typically an intentional protection setting. 

• Option A: Remove IRM from that library (if business rules allow) 
  Site owners or SharePoint admins can turn off IRM for the library by changing the library’s Information Rights Management settings. 
• Option B: Keep IRM, move the notebook to a non IRM library 
  If the library must remain IRM protected for compliance, the reliable forward path is to host the OneNote notebook in a different SharePoint library that does not have IRM enabled.

6. Contact Microsoft Support

If the issue persists after trying these steps, the best next step would be to have your IT administrator open a support ticket with Microsoft via the admin center. A technical support engineer can then initiate a remote session, review backend settings, and run diagnostics. If needed, they can escalate the case to specialized engineering teams who are well-equipped to perform advanced troubleshooting and provide targeted solutions.

Answer 2

The error code 0xE0000644 typically indicates a synchronization issue with OneNote, particularly when documents are stored in SharePoint. Here are some suggestions to resolve this issue:

1. Check Internet Connection: Ensure that you have a stable internet connection, as sync issues can occur when you are offline.
2. Sign In: Make sure you are signed in to your Microsoft account in OneNote. If you are not authenticated, it may prevent syncing.
3. Sync Status: Check the sync status of your OneNote notebook. You can do this by right-clicking on the notebook in OneNote and selecting "Sync" to manually initiate a sync.
4. Notebook Location: Verify that the notebook is correctly stored in SharePoint and that you have access permissions to it.
5. Update OneNote: Ensure that you are using the latest version of OneNote, as updates may contain fixes for known issues.
6. Clear Cache: Sometimes clearing the cache of OneNote can help resolve sync issues. You can do this by closing OneNote, navigating to the cache folder, and deleting the contents.
7. Check for Conflicts: Look for any conflicting changes in the notebook that might be causing the sync to fail.

If these steps do not resolve the issue, you may want to consult Microsoft support for further assistance.
