How to Stop OneNote from Opening All Notebooks Automatically
Question details
The user wants to prevent OneNote from automatically opening and synchronizing hundreds of personal and shared notebooks when setting up a new computer.

- Product
- Microsoft OneNote
- Device & OS
- Windows 11
- Scenario
- Setting up Microsoft OneNote on a new or temporary computer connected to multiple accounts.
- Observed behavior
- OneNote automatically opens and attempts to synchronize every notebook associated with the user's OneDrive accounts, causing unnecessary background syncs and cluttering the workspace.
Ensure that any local changes in your currently open notebooks have successfully synchronized to OneDrive before you begin closing them to avoid accidental data loss.
Manually Close Unwanted Notebooks
Because OneNote natively reopens previously accessed notebooks and lacks a 'close all' button, you must close unnecessary notebooks individually.
Microsoft OneNote is designed to remember the notebooks you had open previously. When signing into a new device with an account that has many active notebooks, it may attempt to load them all. You will need to manually curate your workspace.
Launch the Microsoft OneNote application on your new or temporary computer.
Navigate to the left-hand panel where all your active notebooks are listed.
Right-click the name of the notebook you do not need right now, and select 'Close This Notebook' from the dropdown menu.
Repeat the previous step for all hundreds of unwanted personal and shared notebooks until only your currently needed notebooks remain open.

Reset OneNote Cache and Selectively Open Notebooks
If OneNote continues forcing all notebooks open even after closing them, clearing the app cache will give you a clean slate to manually open only the ones you need.
Looking for a Lighter Productivity Solution? Try WPS Office
If heavy background synchronization and automatic application behaviors in Microsoft Office are slowing down your temporary or new computers, consider switching to WPS Office. It provides a lightweight, highly compatible alternative for your document management needs.
- 1. Download WPS Office: Visit the official WPS website and download the free installation package for your Windows PC.
- 2. Install the Software: Run the installer and follow the simple on-screen instructions to set up WPS Office.
- 3. Manage Files on Your Terms: Open WPS Office and manually access only the documents you need without worrying about aggressive background syncing.

Frequently Asked Questions
Is there a single button or command to close all OneNote notebooks at once?
No, Microsoft OneNote does not currently have a 'Close All Notebooks' feature. You must right-click and select 'Close This Notebook' for each one individually.
Why does OneNote automatically open notebooks on a new computer?
When you sign into a new device with your Microsoft 365 or OneDrive account, OneNote attempts to restore your previous workspace state by opening the notebooks that were marked as actively open in the cloud for that account.
Can I prevent shared notebooks from automatically appearing?
Shared notebooks behave similarly to personal ones. If they were previously left open in your OneNote environment, the application will attempt to load them. You can prevent this by explicitly closing them in the desktop app before logging into a new temporary computer.
