    Hello Higgins, Jennifer,

    You may refer to the following Microsoft Support articles for guidance on syncing and troubleshooting OneNote on your iPhone or iPad:

    Since the current description does not include the exact behavior or any error details, it is difficult to determine the specific cause of the issue at this stage. If the information in these articles does not resolve the issue and you would like more detailed assistance, please provide some additional information, such as:

    • What exactly happens when you try to sync the notebook?
    • Do you receive an error message or error code? If so, please provide the complete message or a screenshot.
    • Does the issue occur on the iPhone, the iPad, or both devices?
    • Does the issue affect only one notebook, or are multiple notebooks affected?
    • Are recent changes missing, or is the notebook unable to sync at all?
    • Can you open the affected notebook and see the latest content in OneNote for the web?
    • Is the notebook stored in OneDrive or SharePoint?
    • Have you already updated OneNote and iOS to the latest available versions?

    These details will help me better understand whether the issue is related to a specific notebook, the OneNote application on the device, the account, or the connection to the notebook’s storage location. I can then provide guidance that is more relevant to the exact issue you are experiencing.

    I hope this information helps.

    Best regards,

    Use Microsoft’s current centralized Fix issues when you can't sync OneNote guide; it covers OneNote on iPhone and iPad and supersedes relying on older issue-specific articles.^1^

    Current iPhone and iPad procedure

    Before signing out, closing notebooks, resetting credentials, or reinstalling OneNote, copy any recent unsynced notes somewhere safe. Microsoft warns that these actions can cause loss of changes that exist only on the device.^1^

    1. Check the notebook in OneNote for the web
      • Open https://www.onenote.com in Safari and sign in with the same work or school account.
      • Open the affected notebook and check whether the latest pages appear.
      • If the notebook does not open in the browser, the problem is not limited to the iPhone or iPad. For a SharePoint-hosted notebook, contact the Microsoft 365 or SharePoint administrator.
    2. Trigger an iOS synchronization
      • Open OneNote and leave it in the foreground.
      • Return to the Notebooks list.
      • Pull down on the list until the spinning progress indicator appears.
      • Leave OneNote open while it attempts to synchronize.
      OneNote for iOS does not provide a separate Sync Now command for an individual notebook; pulling down the Notebooks list attempts to resynchronize the open notebooks.^1^
    3. Update OneNote
      • Open the iOS/iPadOS App Store.
      • Search for Microsoft OneNote and install an update if offered.
      • If other Microsoft 365 apps are installed, update those as well because Office apps share sign-in credentials.
    4. Reset the OneNote account session only after safeguarding unsynced notes
      • On iPad: OneNote → gear icon in the upper-right.
      • On iPhone: OneNote → … → Settings.
      • Under Account, select the affected account, select it again, and choose Remove Account.
      • Close OneNote completely, reopen it, and sign in again.^1^

    Narrow down the failure

    • One notebook or section fails: On a desktop where the notebook is current, create a new section and **copy—not move—**the affected pages into it. Sync the notebook and verify the copies appear on iOS before deleting anything.
    • All notebooks fail only on one iPhone or iPad: This points toward the device’s app session or credentials; use the account-reset procedure above.
    • The notebook also fails in OneNote for the web: For a business notebook stored in SharePoint, have the administrator check access and service health.
    • An error code appears: Record the complete code and message; the current guide contains code-specific branches and may show a Get Help option.^1^

    The OneNote for iPhone support hub also links to the current iOS sync troubleshooting material.^2^ The separate recent issues page should not be treated as a newer sync article: its displayed update date is February 2020 and several entries are from 2017–2018.^3^
