A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
Hello,
The quickest way to get it back on an iPad is to restore it from the notebook recycle bin using OneNote for the web in Safari. On your iPad, open Safari and go to onenote.com, then sign in with the same account you use in the OneNote app.
Open the same notebook where you swiped the page away. In the top bar choose the View tab, then Deleted Notes. Find your page, tap and hold it, choose Restore To, pick the section you want, and confirm. Switch back to the OneNote app and pull down to refresh the section so the page reappears. OneNote keeps deleted pages in the notebook recycle bin for 60 days before they are permanently removed.
What you saw on iPad is expected. Swipe to delete on iPad is immediate and the app does not offer Undo for page deletions, which is why it seemed to vanish without a prompt. The recycle bin safety net is at the notebook level and is accessible from OneNote on the web or desktop.
If you do not see the page in Deleted Notes, make sure you are in the right notebook and account and that it was deleted less than 60 days ago.
If you still cannot find it, tell me roughly when it was deleted and where the notebook is stored, OneDrive or SharePoint, and I will guide you on the next best step.
