8 Ways to Fixed OneNote Not Syncing [Get Connected]

OneNote Not Syncing

Microsoft One Note is one of the best apps designed for taking notes, compiling research data, and organizing information that you’ll regularly need. What makes it more convenient is that it works virtually everywhere across different devices.

To ensure that you can effortlessly access your files, OneNote syncs notes, files, and data and then stores them in the cloud using OneDrive.

However, sometimes OneDrive might run into problems preventing it from working as expected. Therefore, if your OneNote is not syncing, there are a few things you can try to restore your connection.

Connection error of OneNote

OneNote might stop syncing because of various reasons. It could be because of your internet connection, having several people working on a notebook, file corruption, or when working on the same notebook from different devices. Whatever the reason, here is what you can do to restore your connection when OneNote doesn’t sync.

1. Check the OneNote Service Status

Check the OneNote Service Status

Before diving into trying to fix the OneNote won't sync problem, you should first check whether it is a server-side problem. OneNote could be down, making it unable to work as expected. Therefore, you can start by opening OneNote Online and checking if everything is updated.

If that’s not the case, you can visit the Office Service Status page on your browser. If you find any problems listed next to Office for the web (Consumer), there is nothing you can do other than wait for Microsoft to fix the issue.

In most cases, your app is experiencing server-side problems if you see the error codes 0xE000078B and 0xE4020040 in OneNote.

2. Force-Sync OneNote

If you receive the 0xE000002E error code when OneNote fails to sync, you can try fixing the issue by force syncing your data. This problem also happens when you share OneNote with other people. Therefore, when you realize that a section of OneNote is not syncing, you can manually sync it. All you have to do is:

Step 1: Right-click on the problematic notebook. Select Sync.

Step 2: Then click on Sync This Notebook

Sync This Notebook

3. Reset the sync connection

Check your OneDrive storage space

The OneNote sync error can also be caused by a lack of enough storage space. If you have a OneNote not syncing problem with the error code 0xE00015E0, you do not have enough space, or your notebook is too large to sync. You can solve this problem by optimizing your files or deleting unnecessary files. Here are ways you can remove this error:

Step 1: In the Save & back up window, look for the Backup section

Save & back up window

Step 2: Next to the Number of backup copies to keep, adjust the number of copies depending on the available space
