Class Notebooks are the part you'll miss most — here's why
Of all the workloads in your school Microsoft 365 account, OneNote class notebooks are the ones leavers most regret losing. Why they're disproportionately valuable, and why they're disproportionately hard to take with you.
Ask any cohort of recent leavers what they wish they'd kept from their school Microsoft account. The most common answer isn't OneDrive files, isn't email, isn't presentations. It's their class OneNote notebooks.
This is true even though class notebooks are technically the smallest workload by storage volume. A typical class notebook is a few hundred megabytes; a typical OneDrive is several gigabytes. The reason notebooks dominate the regret list isn't size — it's density of value.
What's actually in a class notebook
A class notebook is structured into three areas:
- Content Library — read-only material the teacher pushes out: handouts, presentations, exam papers, marking schemes.
- Collaboration Space — shared workspace for the class.
- Student section groups — one per student, where each individual's work lives.
Your section group inside the class notebook is the part that's yours. Every page you typed, every photo of the whiteboard you pasted in, every annotated worksheet your teacher returned to you, every revision note you made the night before an exam. The content library has the teacher's material; your section group has the working record of how you, specifically, thought about the subject.
That working record is the thing that's hard to reconstruct later from any other source.
Why it's hard to take with you
The class notebook itself is owned by the class — technically, by the SharePoint site that hosts the class team. You don't own it. Microsoft's OneNote export tools enforce this: File → Export Notebook is greyed out for notebooks you don't own, on both Windows and Mac.
The official Microsoft answers for "how do I get my work out" are unsatisfying:
- Send as PDF flattens the entire notebook into one document, losing structure, page hierarchy, embedded files, ink layers and links between pages. Useless for actually using your notes later.
- Copy individual pages to a personal notebook works, but for a four-section notebook with sixty pages you're doing this hundreds of times.
- Screenshot every page is what students actually end up doing, and the result is a folder of images you can't search and can't extract text from.
None of these is what you want.
The shape of a good export
What you actually want is the raw .one section files from your own section group, with section names preserved, openable in OneNote on a personal account. That gives you the original structure, your pages in the same hierarchy, all the embedded content intact.
That's what mydocs.school produces. It's also what SharePoint can produce if your school's IT policy allows you to download the underlying files directly from the class's SharePoint site. The mechanism is the same: pull the raw .one files via Microsoft Graph (or SharePoint document library), scope to your own section group, deliver them packaged.
The privacy boundary is critical. Class notebooks aren't yours to redistribute wholesale — teacher pages and other students' sections aren't yours. The export has to filter to your section group only. mydocs.school does this with two layers of enforcement: SharePoint ACLs only return your own section group at the API level, and the application re-checks the section name against your account before adding any file to the zip.
What you'll miss in particular
In approximate order of how often alumni come back asking for them:
- Sciences (Biology, Chemistry, Physics) — class notebooks with the teacher's explanations of specific topics, often more useful as university revision than any textbook.
- Maths — worked examples and your own annotated approaches to past papers.
- Languages — vocabulary lists, grammar notes, your own translations with teacher corrections.
- English Literature — close-reading notes, teacher annotations on essay drafts.
- History — source analyses, essay plans.
- Geography — fieldwork notes, sketches with your teacher's marginalia.
The pattern: subjects where the teacher's intellectual contribution to the page is high. The pages aren't just notes you wrote; they're a record of the conversation between you and your teacher on the topic, frozen in time.
What to do about it
If your school is on mydocs.school: sign in and download. The class notebooks come through as section-by-section .one files, openable in any OneNote.
If your school isn't onboarded:
- Try the SharePoint route. Some schools allow direct download of
.onefiles from the class's SharePoint document library. Worth checking before assuming it's blocked. - Ask your IT team if they can export your section group manually. They can — it's an admin task in SharePoint — but it's not always feasible at cohort scale.
- Failing both: copy pages individually into a personal notebook before your account closes. Tedious, but reliable.
A note on the format
If you do end up with raw .one files, the lifecycle goes:
- Sign in to OneNote on a personal Microsoft account (free).
- Create a new personal notebook to hold the imports.
- File → Open → select the
.onefile. The section appears inside your personal notebook. - Optional but recommended: once imported, export to PDF as a secondary archive. PDF is more format-stable for the long term;
.oneis fine for the next decade but isn't a forever format.
That .one file is the closest thing to a faithful copy of your original work. Treat it as the canonical archive.
The bigger picture
The reason class notebooks dominate the regret list is that they're the workload where the institution's tooling chose convenience for the school over portability for the student. It's a structural choice — class notebooks are designed to be owned by the class so the teacher can manage them — but the consequence is that the student's own work becomes hard to take with them.
mydocs.school exists, in significant part, to fix that specific asymmetry. The OneDrive part of the workflow is convenient; Microsoft does most of that work. The OneNote class notebook part is the hard part, and it's the part most leavers most need.
If you're reading this in your final term: take twenty minutes. Sign in. Download. Open one of the .one files on a personal account to confirm it works. You'll be glad.
