Opening two OneNote windows simultaneously can be a game-changer for productivity. Whether you're juggling multiple notebooks or just want to compare notes side by side, having dual windows can make your life a lot easier. This post will guide you through the steps to accomplish just that, with a few helpful tips sprinkled in along the way.
Understanding the Need for Multiple Windows
Before we jump into the how-to, let's take a moment to consider why you might want to have two OneNote windows open at the same time. Imagine you're working on a research project. You've got notes in one section, and you're compiling a report in another. Without the ability to view both at once, you're stuck switching back and forth, losing your train of thought with each click.
Having two OneNote windows open allows you to:
- Compare notes from different sections or notebooks.
- Efficiently transfer information between notebooks.
- Keep reference material open while writing or brainstorming.
- Boost productivity by reducing the need to click around constantly.
Now that we've established the why, let's move on to the how.
Opening Two OneNote Windows on Windows
If you're using OneNote on Windows, you're in luck because the process is relatively straightforward. Here's what you need to do:
- Open OneNote on your computer as you usually would.
- Once OneNote is open, right-click the OneNote icon in your taskbar.
- Select "OneNote" from the list that appears. This action opens a new window.
- In the new window, navigate to the notebook or section you want to view.
And there you have it. You've successfully opened two instances of OneNote on your desktop.
Interestingly enough, this method allows you to drag and drop content between the two windows. So, if you're compiling notes from different sections, it becomes a breeze. Just click, drag, and drop. Easy, right?
Opening Two OneNote Windows on Mac
For Mac users, the process is slightly different but just as easy. Here's how you can open two OneNote windows on a Mac:
- Open OneNote from your Applications folder or via Spotlight Search.
- Once opened, go to the menu bar and click on "File."
- Select "New Window" from the dropdown menu.
- Navigate to the notebook or section you'd like to access in this new window.
Now you've got two windows open on your Mac. Feel free to arrange them side by side for easy viewing. This setup is particularly useful if you're working on a MacBook with an external monitor, offering a larger workspace for your notes.
And while you're at it, you might want to check out how Spell can help you create high-quality documents faster than ever. With AI built into the document editor, you can draft, edit, and refine your notes in no time.

Using OneNote Online for Multiple Windows
If you prefer using OneNote Online, the web version of OneNote, you can also open two instances in different browser tabs. This method is useful if you're working on a Chromebook or a shared computer. Here's how:
- Open your preferred web browser and navigate to the OneNote website.
- Log into your Microsoft account if prompted.
- Once logged in, open the notebook you want to view.
- Open a new tab in your browser and go back to the OneNote website.
- Log in again (if necessary) and open the second notebook or section.
Now, you can switch between the tabs or arrange them side by side if your browser supports tab tiling. This setup is particularly handy if you're working with multiple notebooks stored in the cloud.
Utilizing Split Screen for Better Organization
One of the great features of modern operating systems is the ability to split your screen between two applications. Whether you're using Windows or Mac, here's how you can set up a split screen for OneNote:
On Windows:
- Open both OneNote windows as described earlier.
- Click and drag one window to the left or right edge of your screen.
- Release the mouse button when you see a transparent outline appear.
- Select the second OneNote window from the available options to fill the other half of the screen.
On Mac:
- Open both OneNote windows.
- Click and hold the green button in the upper-left corner of one of the windows.
- Select "Tile Window to Left of Screen" or "Tile Window to Right of Screen."
- Choose the second OneNote window for the other half of the screen.
This setup allows you to work more efficiently by keeping everything you need in view. It's like having two desks in one, giving you space to spread out and focus on what matters.
Making the Most of OneNote's Features
Now that you've got two windows open, it's time to explore some of OneNote's features that can help you manage notes even better:
- Tags: Use tags to categorize and prioritize notes. You can quickly find tagged notes using the search function.
- Quick Notes: Jot down ideas or reminders without opening a full notebook. Quick Notes are accessible from any OneNote window.
- Notebook sharing: Collaborate with colleagues or friends by sharing your notebook. This feature is handy for team projects or study groups.
- Audio and video notes: Record meetings or lectures directly in OneNote. These multimedia notes sync across all devices.
These features can enhance your note-taking experience, making it easier to organize and retrieve information when you need it.
Comparing Notes: Side-by-Side Review
Once you have your dual windows open, you can start comparing notes side by side. This practice is particularly useful if you're revising a document or preparing for a presentation. Here's how to make the most of this setup:
- Identify differences: Use the side-by-side view to spot discrepancies between sections or notebooks. This method is great for proofreading or ensuring consistency in your work.
- Consolidate information: Easily transfer information between windows by copying and pasting text, images, or even entire pages.
- Reference material: Keep reference material open in one window while writing or brainstorming in the other. This method reduces the need to switch back and forth, allowing you to maintain focus.
By using OneNote's multiple windows and features, you can streamline your workflow and boost your productivity.


Troubleshooting Common Issues
While opening two OneNote windows is usually a smooth process, you might encounter some hiccups along the way. Here are a few common issues and how to solve them:
- Can't open a new window: If right-clicking the taskbar icon doesn't work, try opening OneNote from the Start menu or Applications folder a second time.
- Performance issues: If your computer slows down with two windows open, ensure other applications are closed to free up system resources.
- Syncing problems: Make sure OneNote is connected to the internet for cloud-based notebooks to sync correctly.
- Display issues: If the windows are not displaying properly, try adjusting your screen resolution or updating your graphics drivers.
By troubleshooting these common issues, you can enjoy a smooth and efficient experience with OneNote.
