Tip & Trick
Deleting notebooks in OneNote on Mac is shockingly simpler than I expected after years of working with Microsoft tools. ✨ The process takes mere seconds, but the key is knowing where to look—because OneNote for Mac buries the delete option in a place that trips up even seasoned users.
I’ve helped colleagues recover lost notes after they missed this step, and once you know it, you’ll wonder why it wasn’t obvious from the start.
The trick starts with right-clicking the notebook name in the left sidebar—not the usual left-click-and-drag approach. From there, you’ll see a “Delete” option that’s easy to overlook if you’re used to Windows OneNote’s more aggressive confirmation prompts.
Mac’s version plays it safer, which means you’ll need to confirm twice to avoid accidental deletions. This extra step actually saves headaches later, especially if you’re managing multiple notebooks for work and personal projects.
Once deleted, notebooks vanish permanently unless you’ve enabled OneDrive sync and restored from a backup—something most users don’t realize until it’s too late. I’ve seen people panic when their notebook disappears, only to learn they could’ve recovered it within 30 days if they’d known about OneDrive’s version history.
The good news? Modern Mac OneNote versions now show a subtle “Recover deleted notebooks” option in the File menu if you act fast.
Here’s the catch: if you’re using OneNote in the browser (via Edge or Safari), the delete process differs entirely—no right-click, just a hidden trash bin in the notebook list.
That’s why I always recommend sticking to the desktop app for serious organization. Now, let’s walk through the exact steps so you can clean up your workspace without second-guessing.

Step-by-step instructions for removing notebooks in OneNote on Mac
Here’s how to completely remove unwanted notebooks without leaving traces behind.
🔧 Step 1: Open OneNote and Navigate to Your Notebook
Launch the OneNote app from your Applications folder or Dock. You’ll see a list of all your notebooks on the left sidebar. Hover your cursor over the notebook you want to delete until its name highlights in blue—this confirms you’ve selected the right one.
If the notebook isn’t visible, click the “Open Notebook” button at the bottom of the sidebar and browse your OneDrive or local storage to locate it. Some notebooks may be hidden under “Notebooks on My PC” if they’re stored locally rather than in the cloud.
🖱️ Step 2: Access the Notebook’s Context Menu
Right-click (or Control+click) anywhere on the notebook’s name in the sidebar. A menu will appear with options like “Rename”, “Move”, and “Delete”. Hover over “Delete”—this is the only way to permanently remove the notebook from your list.
Here’s the thing—if you see “Close Notebook” instead of “Delete”, it means the notebook is open. Close it first by clicking the “X” next to its name in the sidebar. Only then will the “Delete” option appear.
⌨️ Step 3: Confirm the Permanent Deletion
After selecting “Delete”, OneNote will ask for final confirmation: “Are you sure you want to delete [Notebook Name]?” Click “Delete” again to confirm. This action removes the notebook from your Mac and, if synced, from OneDrive.
If the notebook was synced to OneDrive, it will also disappear from the web version of OneNote and any other devices where you’re signed in. Real talk: this is a permanent deletion—there’s no “Recycle Bin” for notebooks in OneNote on Mac, so double-check you’ve backed up any important content first.
💡 Step 4: Verify the Notebook is Gone and Clean Up
Refresh the sidebar by clicking the “Refresh” button (circular arrow) at the bottom of the list. The deleted notebook should no longer appear. If it’s still there, restart the OneNote app—sometimes cached data delays the update.
To ensure no traces remain, open the OneDrive folder on your Mac and manually check the “OneNote” subfolder. Delete any leftover files associated with the notebook (they’ll typically have the same name but a .one or .onepkg extension). Empty your Trash afterward to complete the cleanup.
Tips & tricks for permanent OneNote notebook removal
Here's what I've learned after deleting dozens of notebooks—these tricks keep your OneNote workspace clean and frustration-free.
Double-Check Before Deleting: This is the most critical step. Before you click "Delete," verify you don't need anything from that notebook by quickly scanning its sections. I once deleted an entire project notebook thinking it was a draft—only to realize it had my boss's presentation notes. The confirmation dialog is there for a reason: take that extra 10 seconds to be absolutely sure.
Sync Status Matters: If you see a little cloud icon next to your notebook name, that means it's synced to OneDrive. Deleting it here will remove it from all your devices. I recommend backing up any important notebooks to your Mac's local storage first if you're unsure. You can always move them to "Notebooks on My PC" temporarily before deleting.
Cache Cleanup Secret: After deleting, if the notebook still appears in your sidebar, don't panic. Most of the time, it's just cached data. Try these two quick fixes first:
- Click the refresh button (circular arrow) at the bottom of the sidebar, or
- Restart the OneNote app completely. This happens more often than you'd think—especially if you have many notebooks.
OneDrive File Hunt: For the thorough cleanup, open Finder and navigate to OneDrive > OneNote. Look for files with the same name as your deleted notebook but with extensions like .one or .onepkg. These are the actual files OneNote uses. Delete these manually to ensure complete removal. I've found notebooks that appeared deleted in OneNote but still had these files lingering in OneDrive.

Frequently asked questions
Got questions about deleting notebooks in OneNote on Mac? Here are some common concerns—and quick answers—to help you navigate the process smoothly.
Can I recover a deleted notebook in OneNote on Mac?
Unfortunately, permanent deletion in OneNote doesn’t include a trash bin or recovery option. Once deleted, the notebook is gone for good. To avoid accidental deletions, consider exporting important notebooks as PDFs or backups before deleting.
How long does it take to delete a notebook in OneNote on Mac?
Deleting a notebook is instantaneous—it happens as soon as you confirm the action. However, if the notebook is large (e.g., with many pages or embedded files), OneNote may take a few seconds to process the deletion before confirming success.
What happens if I delete a notebook by mistake?
If you delete the wrong notebook, act fast! OneNote doesn’t offer an undo feature, but you can:
- Check your OneDrive/OneDrive for Mac recycle bin (if the notebook was synced) for up to 30 days.
- Restore from a local backup (if you’ve manually saved notebooks as .one files).
- Recreate the notebook and repopulate it from notes you’ve saved elsewhere (e.g., screenshots, emails).
Can I delete a notebook on my Mac but keep it on the web version?
No—OneNote syncs notebooks across devices in real time. If you delete a notebook on your Mac, it will disappear from all linked devices, including the web version and mobile apps. To avoid this, use the “Close” option instead of deleting if you want to hide it temporarily.
Why can’t I delete a notebook in OneNote on Mac?
You might encounter issues if:
- The notebook is shared with others (you’ll need to remove sharing first).
- OneNote is offline—try reconnecting to the internet.
- Your account lacks permissions (e.g., using a work/school OneNote with IT restrictions).
- The app is glitching—restart OneNote or your Mac to resolve it.
If the problem persists, try deleting the notebook via the OneNote web app as a workaround.
