Why OneNote backups are paused and how to restore them?

Microsoft deprecated the old OneNote APIs on March 31, 2025, and now requires separate authorization to back up OneNote content.

Because of this change, SysCloud can no longer perform new backups of your SharePoint-based OneNote notebooks, sections, and pages.

To resume OneNote backups, you need to complete a new authorization flow that explicitly grants the updated OneNote access required by Microsoft.

Here’s what to do:

1. Log in to your SysCloud dashboard.

2. Go to the Cloud connection section.

3. Click “Add accounts” in the Microsoft 365 side tray.

4. Connect the account using MS 365 account's admin credentials. 
   
   

Note: Once this is done, SysCloud will automatically resume backing up your OneNote notebooks, sections, and pages.

Enhancing security with changes to OneNote Class Notebook APIs
