This worked for me, but it took well over an hour to rebuild the cache since it has over 7,000 files in it. Not very long ago I had to deal with a sync error (below) that blew my entire day rebuilding multiple Notebooks from backups I took when the problem
presented itself.
These sync / access issues are starting to pile up and it's killing me. I have my entire brain and my life in OneNote so any disruptions or loss of information has a huge negative impact. I'm trying to share a notebook inside my company and due to credential
issues it's been unsuccessful so far. People utilize multiple Microsoft services for SharePoint, Skype, Live, etc. and we can't find the proper account that allows OneNote desktop update access and still use their existing service - they can use the Web interface,
but that is not nearly as functional or fast as the desktop version.
For anyone reading this - be Extremely careful when using multiple Microsoft accounts for personal and professional purposes because OneNote / OneDrive absolutely
does not like more than one account utilized on your client for accessing more than one notebook - e.g. a separate OneNote notebook for collaboration at work associated with a business OneDrive share and a private
personal notebook for sharing with your family associated with Hotmail/Outlook/Live ID and its OneDrive share.
The sync error I received:
"An error occurred while attempting to sync this section or notebook. (Error code: 0xE4020030)"
