Additional Steps

Large notebooks

If your notebook has a particularly large section, you might want to create a new notebook for just that section. Creating a second notebook can speed things up if you have lots of content.

Try following these other tips to improve the responsiveness of the app:

  • Reduce the number of sections in your notebook.

  • Reduce the number of pages in a section.

  • Reduce the amount of content on each page.

To view how much storage space OneNote and your notebooks are using, do the following:

  1. Tap Settings on the Home screen.

  2. Tap General, and then do one of the following:

    • If you’re using an iPad, tap iPad Storage.

    • If you’re using an iPhone, tap iPhone Storage.

  3. Scroll down and find OneNote in the list of apps to see the amount of space that OneNote is using.

  4. Scroll back to the top to see how much local storage space is remaining on your device.

If OneNote is using up more storage than you’d like, try closing any notebooks that you’re not using. This will free up space on your device and improve OneNote’s responsiveness.

If the storage space on your iPad is nearly full, either enable the Optimize Photos and/or Review Large Attachments options, or delete any necessary apps from your device.

Syncing notebooks

When you sync your notebooks for the first time, it can take a while, depending on your network speed and on the number of notebooks you’re syncing.

Wait until all of your notebooks have completed syncing before using OneNote.
