Change your network connection

Connect your device to a different Wi-Fi network, or use your mobile phone's hotspot to see if the synchronization completes successfully.

Identify unsynchronized notes

Look for a yellow warning triangle or a red 'X' sync icon over your notebook sections or pages to identify exactly which content has not been uploaded to the cloud.

Copy content to a local application

Open a reliable text editor like Word or Notepad, and manually copy and paste all unsynced text, images, and attachments from OneNote into the new document to serve as a temporary backup.
