all. I have a few SharePoint 2010 libraries configured to use document sets. The document set content type is configured to provide an Open Notebook.onetoc2 by default. OneNote 2010 uses the document set as the notebook container folder, allowing all of the notebook's contents to be stored in the document set. It works great.
However, we're now experiencing a problem with this method since several users have upgraded to OneNote 2013. If a user with contribute permissions opens a notebook stored in a document set with OneNote 2013, the document set's icon changes to that of a OneNote folder. The document set's properties still report it to be a document set, but it no longer behaves as one. Clicking it either tries to open the notebook (if Office web apps are enabled) or takes the user into the document set as if it were a normal folder.
I don't know if this is a bug or behavior by design. Either way, I haven't been able to find any information on it. Any advice would be greatly appreciated. Thanks!
