A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
Same issue. I deleted the unwanted notebooks from EVERY single place I could find them AND deleted all of my recycle and trash bins. On my desktop, OneDrive on my desktop, OneDrive/sharepoint, OneNote Online. I finally found one more delete button after reading through all the posts and opening OneNote through office online and clicking on recent. After choosing recent, I right clicked on the file and low and behold a "Delete" button with a "New" icon next to it. I click on that... and a pop up asks if I'm sure...yes!...another pop up. "Can't delete this item. This item doesn’t exist. It may have already been deleted." You gotta be kidding me. I know I deleted the item, but it is still there!!!! It did have a hide button also, so I'm just gonna try that and see if it will go away from all the places I keep finding them.
This all really started when I tried to use OneNote on my iPad. I'm a windows laptop user, but want to take notes on my iPad and it's been a nightmare learning how to upload and sync the correct notebooks, because I apparently just kept making copies and nothing would sync properly. I gave up a year ago. Trying again, but first want to delete all the junk ones I can find on my PC. I love the app, but this is ridiculous.
