What are invalid characters?
Certain characters have special meanings when used in file names in OneDrive, SharePoint, Windows and macOS, such as "*" for wildcards, and "\" in file name paths. If a file or folder you’re trying to upload to OneDrive contains any of the characters listed below, it may prevent files and folders from syncing. Rename the file or folder to remove these characters before you upload it.

To rename a file or folder in Windows, select it and press F2. To rename a file or folder on a Mac, select it and press the 'return' key.
Some organizations don't yet support # and % in names. If you're a global admin or SharePoint admin in Microsoft 365, see Enabling # and % Support on the SharePoint blog to learn how to allow these characters.

How are OneNote notebooks synced?
OneNote notebooks have their own sync mechanism outside of OneDrive. If you plan on sharing a OneNote notebook—with yourself or others—it's best to create it on OneDrive right from the start.
