Is OneNote acting sluggish and getting on your nerves? You're not alone. Many folks experience slow performance with this handy note-taking tool. It can be downright frustrating. But don't worry, we're here to troubleshoot and explore why OneNote might be dragging its feet and how to speed things up. Whether you're a student, a professional, or anyone in between, understanding these common issues can help you get back to capturing ideas, organizing notes, and getting things done efficiently.
Why OneNote Slows Down
First, let's tackle the most pressing question. Why does OneNote become slow in the first place? The reasons are varied, and it's often a combination of factors rather than a single culprit. Here are some common reasons you might notice a lag:
- Large Notebooks: Over time, notebooks can become bloated with content. This includes text, images, videos, and other attachments that take up space and slow down the app.
- Syncing Issues: OneNote relies heavily on cloud syncing. If there are issues with your internet connection or the cloud service itself, it can slow down the app.
- Outdated Software: Running an older version of OneNote can lead to performance issues, as updates often include speed improvements and bug fixes.
- Device Performance: If your computer or device is running low on resources (like RAM), OneNote may struggle to perform smoothly.
Understanding the cause is the first step in fixing the issue. Now, let's look at some practical ways to get your OneNote running smoothly again.
Managing Large Notebooks
Having a lot of content in OneNote is great. Until it isn't. Large notebooks can be a major factor in slowing down your app. Here are some steps to manage your content:
Archive Old Notes
If you have notes that you no longer need immediate access to, consider archiving them. You can create an archive notebook and move old sections there. This keeps your active notebooks lean and mean, improving performance.
Split Notebooks
Instead of having one enormous notebook, break it down into smaller, topic-specific notebooks. For example, if you're a student, you could have a separate notebook for each subject. This not only speeds up OneNote but also makes it easier to find what you're looking for.
Remove Unnecessary Attachments
Attachments like PDFs, images, and audio files can quickly bloat your notebooks. Consider moving these files to a cloud storage service like OneDrive or Google Drive and linking to them instead. This keeps your notebooks lighter and more responsive.

Improving Syncing Performance
OneNote's cloud-syncing feature is both a blessing and a curse. When it works, it's seamless. When it doesn't, it can slow everything down. Here's how to optimize syncing:
Check Your Internet Connection
It might sound obvious, but a slow or spotty internet connection can wreak havoc on syncing. Make sure you're connected to a reliable network. If possible, use a wired connection to rule out Wi-Fi issues.
Manual Sync
Sometimes, manually syncing your notebooks can resolve issues. In OneNote, click on "File," then "Info," and select "View Sync Status." From here, you can force a sync to ensure everything is up-to-date.
Limit the Number of Devices
OneNote allows you to access your notebooks from multiple devices. However, too many devices syncing simultaneously can cause delays. Limit the number of devices connected to your OneNote account or prioritize which ones sync more frequently.
For a smoother experience, consider using Spell to create and manage documents with AI, which can help streamline your workflow and reduce the hassle of syncing issues.

Keeping OneNote Updated
Software updates are crucial for maintaining speed and performance. Here's why staying updated matters and how to do it:
Why Updates Are Important
Updates often include bug fixes, security patches, and performance improvements. Running an outdated version of OneNote could mean you're missing out on these enhancements.
How to Update OneNote
Updating OneNote is straightforward. If you're using the desktop version, open OneNote, click on "File," then "Account," and select "Update Options." Choose "Update Now" to check for and install any available updates.
Automate Updates
To ensure you never miss an update, set OneNote to update automatically. This way, you'll always have the latest features and improvements without having to think about it.
If you want a document editor that includes AI-driven updates and improvements, Spell offers a seamless experience that keeps your documents fresh and efficient.
Optimizing Device Performance
OneNote's speed isn't just about the app itself. It also depends on your device's performance. Here are some ways to optimize your device:
Free Up RAM
Running too many applications simultaneously can slow down your device. Close unnecessary programs to free up RAM, giving OneNote more resources to work with.
Check for Background Processes
Some background processes can consume significant resources without you realizing it. Use the Task Manager (on Windows) or Activity Monitor (on Mac) to see what's running in the background and close any unnecessary processes.
Regular Maintenance
Regularly clean up your device by deleting temporary files, clearing caches, and running disk cleanup tools. This helps keep your device running smoothly, benefiting all applications, including OneNote.
Understanding OneNote's Cache
OneNote uses a cache to store information temporarily. While this usually speeds things up, a bloated cache can have the opposite effect. Here's how to manage it:
Clear the Cache
Clearing the cache can resolve performance issues. To do this, you'll need to close OneNote first. Then, navigate to the cache folder (usually located in the AppData folder on Windows). Delete the cache files, then restart OneNote.
Adjust Cache Size
If you frequently deal with large notebooks, consider increasing the cache size to improve performance. This can be done by adjusting settings in OneNote's options menu.
Regular Cache Maintenance
Make it a habit to clear the cache periodically, especially if you notice a slowdown in performance. This simple step can make a significant difference.
Using OneNote Add-Ins Wisely
Add-ins can enhance OneNote's functionality, but they can also slow it down. Here's how to manage them effectively:
Review Installed Add-Ins
Check which add-ins are installed and decide if they're all necessary. Disable or remove any that you don't use regularly, as they can consume resources.
Choose Add-Ins Wisely
When adding new features, opt for reputable add-ins known for their efficiency. This ensures you get the functionality you need without compromising speed.


Update Add-Ins
Just like the main application, add-ins need updates too. Regularly check for updates to ensure they run smoothly and don't slow down OneNote.
Considering Alternative Tools
If you've tried everything and OneNote is still sluggish, it might be time to consider alternative tools. There are plenty of note-taking apps out there, each with its strengths and weaknesses:
Evernote
Evernote is a popular choice with robust features for organizing notes and tasks. It's known for its versatility and ease of use, making it a solid alternative to OneNote.
Google Keep
For those who prefer simplicity, Google Keep is a straightforward, no-frills option. It's great for quick notes and reminders, but it may lack some of the advanced features OneNote users are accustomed to.
