I am trying to recover a OneNote folder, but can't seem to get it to open up. Backstory is a co-worker deleted a user's profile and backed up our usual things. Come to find out the user couldn't access the last two years of her OneNote files. Turns out what she saved to her network folder was either renamed or moved, so it hasn't synced up in 2 years. We were able to recover the OneNote files using data recovery stuff and after hours of trying different things we can't seem to fully open it. Not sure if it's somehow tied to her old profile in some way. We know it was all made in OneNote 2016. I've tried to open it in 2010, 2016, and 365 but no luck. I can open the folder name, and see all the notes, but am greeted by the lovely error within the screenshot. Any help?
