    Hi,

    From the message you're seeing: "OneNote can't open this notebook because it has been deleted or moved. The location may not exist or you may not have permission to access it".

    This typically indicates that OneNote is attempting to connect to a notebook stored in OneDrive or SharePoint, but it's currently unable to access that location. This can happen for several reasons. For example, the notebook may have been moved or deleted, you may be signed in with a different Microsoft account, or OneNote may be using outdated cached sign-in information.

    To help narrow down the cause, I'd recommend trying the following steps:

    1/ Check whether the notebook is accessible online:

    First, sign in to OneNote for the web or OneDrive on the web using the same Microsoft account that you're using in the OneNote app.

    Once signed in, check whether the notebook appears in your account and whether it opens successfully in the browser. This will help confirm whether the notebook is still available and accessible.

    2/ Verify that you're signed in with the correct account:

    If the notebook belongs to a work or school account, please make sure that OneNote on your iPhone or iPad is signed in with that exact account.

    In cases where both personal and work accounts are used on the same device, OneNote can sometimes attempt to access the notebook through the wrong account, which may result in this error.

    3/ Check for OneNote updates:

    Next, open the App Store and see whether any updates are available for Microsoft OneNote. Keeping the app up to date can often resolve unexpected syncing or access issues.

    4/ Reset OneNote sign-in information on iOS:

    Before proceeding, please ensure that all important notes have been synced or backed up, especially any content stored in Misplaced Sections.

    Then:

    • Open Settings on your iPhone or iPad.
    • Scroll down and select OneNote.
    • Tap Reset OneNote.
    • Turn on Delete Login Credentials.
    • If necessary, also turn on Delete All Notebooks.
    • Reopen OneNote and sign in again.

    This can help clear outdated account information and allow OneNote to reconnect properly.

    5/ If the notebook was shared with you:

    If the notebook is owned by someone else, it would be worth checking with the owner to confirm that you still have permission to access it.

    Additionally, they may want to verify the sharing settings in OneDrive and, if necessary, reshare the notebook with you.

    If the issue persists after trying these steps, could you please provide a bit more information?

    • Are you signed in with a personal Microsoft account or a work/school account?
    • Are you able to open the notebook successfully in OneNote for the web?
    • Does this happen with all notebooks or only with one specific notebook?
    • Is the notebook stored in OneDrive, SharePoint, or Microsoft Teams?

    Once I have those details, I'll be happy to look into this further with you.

    Kind regards,

    Try these steps in order on the iPad:

    1. Verify the account works in the browser.
      • Open OneNote for the web and sign in with the same account.
      • If the notebook opens there, the account is valid and the issue is likely cached sign-in data in the app.
    2. Reset OneNote sign-in credentials on iPad.
      • Go to iPad Settings > OneNote > Reset OneNote.
      • Turn on Delete Sign-In Credentials.
      • Close OneNote completely, then open it again and sign in.
    3. If that does not help, repeat the reset and also remove local notebook copies.
      • In iPad Settings > OneNote > Reset OneNote, enable Delete All Notebooks only if the notebooks are already synced to OneDrive or SharePoint.
      • This removes local offline copies.
    4. Update OneNote and other Microsoft 365 apps on the iPad.
      • On iPhone and iPad, Microsoft 365 apps share Office credentials.
      • If Word, Excel, PowerPoint, or Outlook are installed, update all of them to the latest version, then try signing in again.
    5. If the app still keeps returning to sign-in, clear the shared iOS Office credentials again.
      • Go to iOS Settings > OneNote > Reset OneNote > Delete Sign-In Credentials.
      • Make sure OneNote is fully closed.
      • Reopen OneNote and sign in again.
    6. If the notebook opens on the web but the app says the notebook was deleted, moved, or access is missing, confirm the same account still has permission to that notebook.
      • This error can happen when the wrong account is signed in, the password was changed, or access to the notebook was removed.

    If the problem started after a password change, sign in again with the same account that owns or was granted access to the notebook.
