One Note sync error E0000024

Question

Last week my one note on the desktop app randomly started asking me to sign in to sync my notebooks and had the error 'E0000024'. No matter how many times I sign in it keeps asking.

I tried to access my personal notebook online and from my one drive but can't find it anywhere - it is only on my desktop app and so am worried I will lose all this work as it is not backed up.

Every other notebook seems to be accessible from the online version except my most recent one that I use daily with all of my current work.

I have tried all solutions I can find but it won't let me log in to sync my notebooks and also I can't open any notebooks from my online version in the app as each time it tells me I am unable to open these as I don't have access.

I have even created a new notebook online as was close to having to copy all my notes across, but it won't even let me open this new notebook in the desktop app

Since this my collaboration spaces have not been working - so I am having to access any updates online.

It all seems like my one note is so separate and not synced, and I am very worried i will lose all of my work in the notebook that can only be found in my desktop app, so please help me sort this!

Hi Thea Thompson,

Thank you for querying in this forum.

I go through the post carefully. It seems like you cannot sync notebooks in OneNote for Mac app as it shows error 'E0000024'. When you go to OneDrive online, one specific notebook cannot be found, other notebooks are accessible from OneNote online.

I do understand the notebook is very important to you and the issue has affected your daily work. Thanks for letting us know the ways you have tried.

May I know if you can access and open that specific notebook in OneNote for Mac desktop app? If yes, please DO NOT close the notebook and DO NOT sign out from OneNote as it has risk of losing un-synced notes.

I wish to try my best to help you. For that specific notebook, I'd like to share following suggestions, you may have a try:

1.You may go to the Recycle Bin of your OneDrive and see if you can find that notebook, if yes, restore it.

2.In your OneDrive, you may also search for the notebook, enter the notebook name in the Search box as below, press Enter and check the result.

3.Besides, generally, recently edited notebook will appear in the notebook list in OneNote Online. You may go to Microsoft 365 home page, click OneNote icon to open OneNote Online home page, check if you can find the notebook.

If you still cannot find the notebook from online, I could understand the frustration and feel very sorry about it.

In this situation, I would recommend you create a new notebook in OneDrive and then open it in OneNote online in browser, then manually back up the notes by copying notes from OneNote desktop app and pasting to OneNote online. I quite understand it will cost much time backing up all the notes of the notebook, but considering the notebook cannot be found in OneDrive, I'm afraid the notes have risk of losing and this way is the most secure method. Thanks for your understanding.

In addition, if you don't want to manually backup the notebook, and considering you have tried opening other notebooks from online version to desktop app but failed. To further troubleshoot the sync issue, if you have OneDrive for business, I sincerely recommend you inform your Microsoft 365 global admin of the issue and ask him to create a support ticket in Microsoft 365 Admin Center > Support > New service request. For reference: How do I find my Microsoft 365 admin 

If you have personal OneDrive, you can directly contact Microsoft Support via this page. Please firstly describe the issue and click Get Help, then click Contact Support on the bottom. Select your product or service(Microsoft 365 and Office), category(Technical Support), Confirm. Then you will get a link to chat with a support agent in web browser.

The support team there has the correct escalation channel for this case. They have higher permission to remotely help you, they also have more resource to investigate the issue further. This is the most efficient way in handling this kind of case for you.

Your patience and understanding are highly appreciated. Hope you are keeping safe and well.

Best regards,

Tina
