Question

OneNote - My entire section randomly dissapeared infront of me

Sher-Shah Madni 10

I had my OneNote open during a lecture, and, with no input from me, I saw my entire section and all my notes disappear right in front of me.

I tried to recover it using methods I found online; however, it did not appear in my deleted notebook history (since I did not delete it). And, the last backup I had was from last week, so I am missing a lot of my work and notes from this past week.

I desperately need help recovering my section, but I do not know what to do. Please help!

I had the exact same situation happen to me just now. An entire section of my notebook just disappeared. Can it be recovered?

Hi Sher-Shah Madni

Thank you for reaching out to Microsoft Q&A Forum and sharing your experience.

I'm sorry to hear about your frustrating experience. Losing notes during a lecture sounds incredibly disruptive, especially with recent work at stake.

To better understand, could you share a bit more details:

What version of OneNote and macOS are you using?
Is this a local notebook or synced to OneDrive/SharePoint?
Did you notice any error messages or unusual behavior before/after the disappearance?

Meanwhile, you can try the recommended steps for recovery process:

You mentioned your last backup was from last week. If it’s a local backup, open OneNote for Mac and go to OneNote > Preferences > Backup. Check the backup location to see if any recent automatic backups were created. To restore, open the backup file directly in OneNote or copy the relevant sections into your current notebook.

If your notebook is synced to OneDrive, try closing and reopening the app or manually forcing a sync.

For further recovery, log in to OneDrive.com using a web browser and check the folder where your notebook resides for any signs of the missing section or files. Even if you didn’t delete anything, manually review the OneDrive Recycle Bin (first stage), the second-stage Recycle Bin, and your Mac’s local Trash in Finder for any orphaned OneNote files.

Since your post includes the "For education" tag, I strongly recommend reaching out to your school's Microsoft 365 administrator immediately. They have the elevated permissions needed for in-depth investigations and can delve into advanced options like detailed version history reviews or specialized recovery tools, potentially uncovering solutions beyond what's available to individual users.

If I have misunderstood your situation, please don't hesitate to clarify, and I will adjust my recommendations accordingly. I'm looking forward to seeing your response soon.
