Free Guide to Deleting OneNote Notebooks

Understanding OneNote Notebooks and Why You Might Delete Them

OneNote is a digital note-taking program made by Microsoft. It works across computers, tablets, and phones, letting people write notes, save images, and organize information in one place. Many people use OneNote for school, work, or personal projects. Over time, you might create many notebooks for different purposes—maybe one for a project that's finished, one for a class you completed, or one you no longer need.

A OneNote notebook is like a digital binder. Inside each notebook, you can have sections (like tabs in a folder), and inside those sections, you can have pages. Notebooks can be stored in different places: on your computer, in OneDrive (Microsoft's cloud storage), or shared with other people through Microsoft 365.

You might want to delete a notebook for several reasons. First, you could be cleaning up old projects to make room on your computer or in your cloud storage. Second, you might have duplicate notebooks and want to keep only one. Third, you might have personal or sensitive information in a notebook you no longer need. Fourth, deleting unused notebooks makes it easier to find the notebooks you actually use every day. According to Microsoft, the average user creates multiple notebooks over time, and managing them helps keep your workspace organized and efficient.

Before you delete any notebook, it's important to understand the difference between deleting locally and deleting from the cloud. Local notebooks exist only on your computer. Cloud-based notebooks exist in OneDrive or SharePoint. Deleting a local notebook removes it from your computer. Deleting a cloud notebook removes it from the internet storage. This guide explains both processes so you understand what happens to your data in each situation.

Practical takeaway: Before starting, identify which notebooks you no longer need and where they're stored—on your computer or in the cloud. This helps you use the right deletion method.

How to Delete Local OneNote Notebooks on Windows

A local notebook is stored only on your computer's hard drive. When you delete a local notebook in OneNote, the program removes it from your notebook list. However, the actual files might still exist on your computer in a folder until you permanently delete them. Here's how to delete a local notebook using OneNote on Windows.

First, open OneNote on your computer. Look at the left side of the screen where all your notebooks appear in a list. Right-click on the notebook you want to delete. A menu will pop up with several options. Look for and click on "Delete Notebook." OneNote will ask you to confirm this action by showing a message that says something like "Are you sure you want to delete this notebook?" Click "Yes" or "Delete" to confirm.

After you delete the notebook from OneNote, the program removes it from your list, but the files might still be on your computer. To completely remove these files, you need to find them in your file system. Local notebooks are usually stored in a folder called "Documents" or a subfolder within Documents. The exact location depends on how you set up OneNote. You can search your computer for the notebook name or look in the "My Documents" folder. Once you find the notebook folder, right-click it and select "Delete." You may need to empty your computer's recycle bin afterward to permanently remove the files.

Some people prefer to keep deleted notebooks in their recycle bin for a while before emptying it. This is smart in case you realize later that you need to recover the notebook. Most computers keep deleted files in the recycle bin for 30 days before they're gone forever. If you change your mind within that time, you can open your recycle bin, find the notebook folder, and restore it to its original location.

Practical takeaway: To fully delete a local notebook on Windows, delete it from OneNote first, then find and delete its folder from your Documents or the location where you stored it. Check your recycle bin settings to know how long files stay there before permanent deletion.

How to Delete OneNote Notebooks from OneDrive or Microsoft 365

Cloud-based notebooks stored in OneDrive or Microsoft 365 work differently than local notebooks. These notebooks exist in Microsoft's internet storage, so they sync across all your devices. If you delete a cloud notebook, it removes the notebook from all devices where you signed in with that Microsoft account. Here's what you need to know about deleting these notebooks.

To delete a cloud notebook using OneNote on your computer, open OneNote and look at your notebook list. Right-click the cloud notebook you want to delete and select "Delete Notebook" or "Move to Recycle Bin." OneNote will ask you to confirm. Click "Yes." The notebook now appears in OneDrive's recycle bin instead of being permanently deleted. This is important because you have time to change your mind—typically 93 days—before OneDrive permanently removes it.

You can also delete cloud notebooks through OneDrive directly. Go to OneDrive.com and sign in with your Microsoft account. Look for the notebook folder you want to delete. Right-click the folder and select "Delete." The notebook goes into OneDrive's recycle bin. To permanently delete it, open OneDrive's recycle bin, find the notebook, and delete it there too. To recover a deleted notebook within the 93-day window, go to OneDrive's recycle bin, right-click the notebook folder, and click "Restore."

If you're using OneNote through Microsoft 365 (the subscription version of Microsoft Office), cloud notebooks might also be stored in SharePoint, which is Microsoft's business document storage system. The process is similar: find the notebook, delete it, and recover it from the recycle bin within 93 days if needed. Be aware that if a notebook is shared with coworkers or classmates, deleting it removes it for everyone, not just you. If you only want to stop seeing a shared notebook on your device, you can "unfollow" or "remove" it instead of deleting it.

Practical takeaway: Cloud notebooks deleted through OneNote or OneDrive go to a recycle bin first, giving you 93 days to recover them. If you delete a shared notebook, other users lose access too, so consider whether you should remove it for yourself instead.

Deleting OneNote Notebooks on Mac, iPad, and Mobile Devices

OneNote works on multiple device types, and the deletion process differs slightly depending on whether you're using a Mac computer, iPad, or phone. Since many people use OneNote across several devices, understanding these differences helps you manage your notebooks everywhere you work.

On a Mac computer, open OneNote and look at the notebook list. Right-click the notebook you want to delete and select "Delete Notebook." Confirm the deletion when prompted. The process is nearly identical to Windows, but the menu options might look slightly different. Like Windows, the deleted notebook might still exist in your Mac's file system, so you may need to find and delete the folder from your Documents or the location where you stored it to completely remove all files.

On an iPad, open the OneNote app and go to your notebook list. Swipe left on the notebook you want to delete. A red "Delete" button appears. Tap it to delete the notebook. On an iPhone or Android phone, the process is similar: open OneNote, find the notebook, swipe left (on iPhone) or long-press (on Android) the notebook, and tap the delete option. These mobile deletions typically only remove the notebook from your device's display, not from the cloud storage where it's saved. To completely delete a cloud notebook used on phones or tablets, you'll need to delete it through OneDrive or OneNote on a computer.

An important note: if you delete a notebook on one device, it doesn't automatically delete from your other devices unless the notebook was cloud-based. For example, if you have a local notebook only on your iPad and delete it there, it won't affect your Mac or computer. However, if you delete a OneDrive-based notebook, it removes from all devices because they all connect to the same cloud storage. Before deleting, verify where the notebook is stored so you understand what will happen across your devices.

Practical takeaway: Mobile devices and Macs use similar delete steps to Windows, but cloud notebooks deleted on any device remove from all your devices. Check storage location before deleting to avoid losing work you might need elsewhere.

Backing Up Information Before Deletion

Deleting a notebook is permanent or semi-permanent, depending on whether it
