I had the identical issue as PaulKougias. (Error code: 0xE000003D)
I believe the issue occurred for me on April 7th? Might have occurred a couple days sooner? April 7th is when I noticed it.
I edit the Notebook on OneNote 2010 on my Desktop computer. I share the Notebook with a colleague, who edits it using Onenote Online (Onedrive?).
The last activity I remember was I had it open on my Desktop computer and my colleague had it open on his Desktop computer, using OneNote Online and was making edits; we both had the same notebook page open.
