Restore the Notebook from the SharePoint Recycle Bin

In most cases, the notebook file was accidentally deleted and can be easily recovered directly from the site's recycle bin.

SharePoint retains deleted items in the site recycle bin for a specific period (usually 93 days). Restoring the deleted notebook from here will immediately re-establish the connection for the Notebook button without requiring further configuration.

1
Navigate to the Project Site

Open your browser and log in to the specific SharePoint Project Online site where the notebook error is occurring.

2
Open the Recycle Bin

Click on 'Recycle bin' in the left-hand navigation pane. If it is not visible, click the 'Gear' icon (Settings) in the top right, select 'Site contents', and then click 'Recycle bin'.

3
Locate the Deleted Notebook

Scroll through the list of deleted items or use the search box to find the missing project notebook.

4
Restore the Item

Check the box next to the deleted notebook, then click the 'Restore' button in the command bar. Try clicking the Site Notebook button again to verify the issue is resolved.

Restore the Notebook from the SharePoint Recycle Bin
Restoration Complete: Once restored, the notebook will return to its original document library, and the Notebook button will automatically detect it again.

Frequently Asked Questions

Why didn't deactivating and reactivating the Site Notebook feature fix the error?

Toggling the Site Notebook feature only resets the configuration link on the SharePoint site. If the actual notebook file was permanently deleted from the document library, resetting the feature cannot recreate the lost data or the file itself.

Where else can I look if the notebook isn't in the standard recycle bin?

If the file is not in the site's primary (first-stage) recycle bin, a Site Collection Administrator can check the second-stage recycle bin. If the file was recently cleared from the first-stage bin, it may still be recoverable from the second-stage bin.

Can I back up my project notes to prevent this error?

Yes. It is highly recommended to periodically export or sync your project notebooks to your local device. Using locally installed software like WPS Office allows you to keep an offline backup of your critical project notes and data.
