Sync and Highlight Text Using a Desktop or iPad

Since the iPhone app lacks a built-in text highlighter, the most reliable method is syncing your notes and highlighting them on a supported device.

The OneNote application for iPhone currently does not feature a native text highlighting tool in its formatting ribbon. However, any highlighting applied on other devices will render perfectly on your iPhone display.

Sync your iPhone notes

Open OneNote on your iPhone, pull down on your notebook list to manually sync, and ensure your recent edits are backed up to your Microsoft account.

2
Open OneNote on a supported device

Launch the OneNote application on your desktop computer (Windows or Mac) or on an iPad and log in with the same Microsoft account.

3
Highlight the text

Navigate to the specific note, select the text you want to emphasize, and click the 'Text Highlight Color' icon located in the Home tab.

4
View the highlights on your iPhone

Allow the notebook to sync. Once completed, open the note on your iPhone, and you will see the highlighted text correctly displayed.
