Hi @Steve MacPhail ,
Could you provide the detail error message about the sync error?
Did you use OneNote on SharePoint?
If yes, you’ll notice that they’re typically stored in Document Libraries. If the SharePoint Library you’re using has certain properties enabled, it could cause sync errors.
Please be a bit more precise to explain your problem or you can upload a screenshot so that I can get more accurate solutions to this problem. I’m glad to help and follow up your reply.
