I have Onenote 2016. Last night one of my notebooks had a sync error (0xE4020017). When I went to the Onenote Online, the Notebook is there and all the section tabs work except one. When it is clicked nothing happens. There is not even an error
notice. It will not open the content. All the other sections were fine.
So, as is the common practice with Onenote errors, I created a new section in my desktop version (labeled "archive"). That showed up in the cloud. I copied over the section. It worked. But later the "archive" section no longer works, except just
before I wrote this review.
I also renamed the affected section, section1. The name transferred but none of the content did. I just get the same error number on the desktop.
I can create a new notebook, add a new section, even write into a new page and it syncs. But when I copy files from the affected section (via an *older backup* so it *cannot be corrupted local backup files*) I get the sync error again.
I have done a quick repair to no avail. I have closed the entire notebook. And I have reopened that notebook's backup into a newly named notebook. The name copied to the cloud. The section name copied. I copied one section (instead of all of them)
but the content is missing again. No error named in the cloud.
Something squirrelly is happening to my cloud service. I pay for that service. MS email support just tells me to go here! Multi-billion company that does not have a redundant system to bypass this problem?
