An error occurred while attempting to sync this section or notebook. (Error code: 0xE4020005)

In Microsoft OneNote 2010, you can share a notebook so that you can access it on other computers or on the Web, or so that you can work in it together with other people. Taking notes as a group is a collaborative process. As a collaborative tool, OneNote offers far more than the ability to send static notebook pages via e-mail.

When you share a notebook on a SharePoint site, you can use the features of a library to manage and share your notebooks. You can manage who has permission to view the notebook or contribute notes. You can store additional information about the notebook or its pages, such as the department name or project number. You can also track versions of the notebook, so that people can view or restore an earlier version if needed and receive updates when the content changes by using alerts or RSS Feeds.
