A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
Most commonly, the notes are not appearing on iPhone because the notebook is not opened there yet, the iPhone app has not synced the notebook, or the notebook format is too old to sync to iPhone.
Try this in order:
- Open the notebook on iPhone
- In OneNote on iPhone, tap More Notebooks at the bottom of the notebooks list.
- Tap the notebook that contains the notes from the MacBook or web version.
- If needed, tap Open more from OneDrive.
- Manually trigger sync on iPhone
- Tap the Show Notebooks button.
- In the notebooks pane, pull down on the notebooks list.
- This starts a sync of open notebooks.
- Search for the notes in the iPhone app
- On any page, tap Search on the bottom menu.
- Enter a keyword from the missing note.
- If the note exists in an opened notebook, it should appear in results.
- Confirm the notebook is stored in OneDrive and opens on the same account
- Since the notes appear on MacBook and on the web, make sure the iPhone app is signed in with that same OneDrive account.
- If the notebook was previously closed on iPhone, it will not appear in searches until reopened.
- Check whether the notebook is in an older format
- Notebooks created in versions earlier than OneNote 2010 for Windows do not sync with OneNote on iPad or iPhone.
- Those notebooks must be updated to the newer notebook format and moved to OneDrive.
- If sync still fails, verify where the problem is
- Open the notebook in OneNote for the web.
- If the notebook and latest changes are visible there, the issue is likely with the iPhone app sync state rather than the notebook content itself.
- Avoid signing out or reinstalling as a first step
- Microsoft warns that signing in or out of OneNote, or removing and reinstalling the app, is not recommended during sync troubleshooting because it can cause data loss.
If the notebook still does not appear after opening it from More Notebooks and pulling down to sync, use the iPhone troubleshooting resources or report the issue in the OneNote community forum.
