A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
OK, for what it's worth I found a workaround for my situation but it's ugly.
In my situation, it was showing me about half a dozen specific notes that it couldn't sync in one of my notebooks. I segregated those to a different 'temporary holding' notebook and then thankfully the main notebook resumed syncing correctly.
But every time I attempted to move back one of the other notes, the sync broke again. It never said why, just that it couldn't sync.
I reorganized my main notebook to have many more sections and section groups, thereby reducing the number of notes I had in each section. Somehow, that allowed the sync to occur even after putting back *all* of the notes.
I shouldn't have had to manipulate the notebook layout this way, but at least it worked for me. Microsoft needs to get in gear and fix this long-standing issue, but hopefully at least my method will work for someone else too.
