这段时间在 OneDrive for Business 上的 OneNote 笔记本出现只读情况，无法进行编辑。
可能是 OneDrive 后台的问题。
只需要额外上传随意一个文件到 OneDrive for Business 就可以了。

Fix for Read only notebook on sharepoint (aka OneDrive For Business)

Thought I'd plug this here:
A number of people have reported having notebooks mysteriously show up as read-only on Sharepoint. The bug responsible has been fixed, but requires you do the following to trigger the "magic" repair process:
1.Visit your OneDrive for Business. Address is usually TENANT-my.sharepoint.com.
2.Upload any file. Triggers Magic.
3.Magic happens. Takes a period of time.
4.Right click and force sync the notebook, which triggers a full hierarchy update
Notebook should be editable.
