How to use Microsoft OneNote: create your first notebook, organize sections and pages, tag and search notes, sync across devices, and use Copilot — the beginner tutorial.

Learning how to use Microsoft OneNote takes about twenty minutes, because OneNote works like a paper binder that lives in the cloud: you open a notebook, add tabbed sections, and fill pages with typed notes, pictures, files, and handwriting. There is no Save button to remember, because OneNote saves everything automatically to OneDrive, and the same notebook opens on your computer, your phone, and the web. This beginner's guide walks through the whole first-use system in order: sign in, create your first notebook, organize sections and pages, tag and search your notes, fix sync problems, and decide whether Copilot is worth paying for.

Students turning readings into revision notes can draft them first with CodexFuse's AI study notes generator, then file the finished notes in OneNote, where they stay searchable alongside everything else. If most of your notes are long, formal documents instead of free-form pages, start with our Microsoft Word beginner guide and use OneNote for the messy middle: meeting notes, research, ideas, and checklists.

What is Microsoft OneNote, and how is it organized?

Microsoft OneNote is a free-form digital notebook: a notebook holds sections, sections hold pages, and pages hold anything you put on them. The structure copies a paper binder, which is why it feels familiar even on the first day. Unlike a word processor, a OneNote page has no fixed margins or flow: you click anywhere on the page and start typing, drop a picture beside a paragraph, and scribble over the top.

OneNote does not force one organizing style on you, and you can reorganize whenever you change your mind. The rule that keeps notebooks usable is simple: one notebook per area of your life, one section per project or subject, and one dated page per meeting or idea. A single giant notebook for everything is the most common beginner mistake, because search slows down and the page list turns into clutter.

How do I create my first notebook in OneNote?

To create your first notebook, sign in with a Microsoft account, choose File, then New, name the notebook, and let OneNote store it in OneDrive. The whole setup takes about five minutes, and you only do it once. Follow these steps in order:

1. Open OneNote on your computer or phone, or go to OneNote on the web, and sign in with your Microsoft account. A free Microsoft account is enough to start; you do not need a paid subscription for the basic app.
2. Choose File, then New, and type a name that describes the area of your life the notebook covers, such as "Work" or "Biology 101." A clear name is worth the ten seconds it takes, because it is what you will search for later.
3. Confirm that OneNote will store the notebook in OneDrive. Cloud storage is what makes automatic saving and syncing work, so a notebook stored only on one device loses the app's main advantage.
4. Add your first section by clicking Add Section and naming it for a project or subject, such as "Meetings" or "Chapter notes." A new section starts with one blank page inside it.
5. Click the title area at the top of that page and type a title with a date in it, such as "Team meeting — Oct 28." Then click anywhere below the title and start typing your first note.

That is the whole first-notebook system: sign in, name the notebook, add a section, title a page, and type. Everything after this point is refinement, not setup. If you already have notes in the old OneNote for Windows 10 app, do not start a fresh notebook for them: sign in with the same Microsoft account in the current OneNote app and your synced notebooks appear there, as explained in the sync section below.

How do I use sections, pages, and subpages without making a mess?

Use sections for topics, pages for individual notes, and subpages only for notes that belong behind another page. Most messy notebooks come from using pages like folders or sections like pages. When a section grows past about twenty pages, split it: either by time, such as "Meetings 2026," or by project, such as "Website launch" versus "Website maintenance."

To add a page, click Add Page in the page list and type a title before you type anything else. A page without a title is hard to find later, because the page list shows titles, not content. If you skip the title, OneNote uses the first line of your notes as the title, which is a decent fallback but a poor habit.

To make a subpage, drag a page tab slightly to the right until its title sits indented under another page. Subpages are ideal for follow-ups: the meeting notes stay on the main page, and the action items live on the subpage behind it. Do not nest deeper than one subpage level, because a notebook with three levels of nesting is a notebook nobody browses.

Two weekly habits keep the structure honest. First, keep an "Inbox" section at the front of each notebook for quick captures, and file those pages into real sections once a week. Second, keep an "Archive" section for anything older than a few months, so your daily sections stay short and current. Ten minutes of tidying a week beats a full afternoon of reorganizing once a year.

How do I take notes on a OneNote page?

Taking notes on a OneNote page means clicking anywhere and typing, because every click starts a separate note box that you can move, resize, and rearrange. This free-form canvas is the feature that separates OneNote from a word processor. You can put a to-do list beside a photo, a quote under a sketch, and a link next to all three, without fighting page layout.

The Home tab holds the formatting you will use daily: bold, bullets, numbered lists, and headings. The Insert tab adds pictures, file attachments, links, tables, and audio recordings to the same page. The Draw tab is for handwriting and sketching with a pen, a mouse, or a finger, and handwriting can later be converted to typed text with Ink to Text. On a touchscreen device, the Draw tab is where OneNote starts to feel like paper.

For meeting notes, use one page per meeting with the date in the title, and put action items in a short list at the bottom of the page. If your meetings live in Outlook, our Microsoft Outlook beginner guide covers the calendar side, and OneNote can pull meeting details from Outlook into a fresh notes page. For numbers that belong in a table instead of a page, our Microsoft Excel beginner guide covers the spreadsheet side, and you can paste a finished table into OneNote as a reference.

What are OneNote tags, and how do I use them?

OneNote tags are small labels you attach to a line of notes, such as To Do or Important, so you can later pull every tagged line into one summary view. Tags turn a notebook from a pile of pages into a task system. The built-in tags cover the cases beginners actually need, and you can create custom tags once the habit sticks.

To tag a line, click on it and choose the tag from the Home tab. To see every tagged line at once, use Find Tags, which builds a summary pane you can scan without opening each page. The discipline that makes tags work is restraint: tag only lines you will act on or look up again. Tagging everything is the same as tagging nothing, because the summary view becomes as long as the notebook itself.

How do I search OneNote and actually find a note?

To search OneNote, press Ctrl+E on Windows or click the search box, type a distinctive word from the note, and narrow the results by notebook, section, or page if the first results are too broad. Search covers typed text across your notebooks, which is why consistent words in page titles matter so much. A page titled "Team meeting — Oct 28" is findable; a page titled "Untitled" is findable only by guessing its contents.

Three habits make search reliable. First, put names, dates, and project words in titles, not just in the body. Second, use the same wording every time for recurring notes, such as "Weekly report" rather than alternating between "report," "update," and "summary." Third, use Find Tags for anything you tagged, because tags are a second search system that ignores wording entirely. If a search still fails, check whether the note is in a notebook that is not open: search only covers notebooks you have open in the app.

How does OneNote sync, and what happens when it doesn't?

OneNote syncs through OneDrive: every change saves automatically to the cloud, and your other devices pick it up when they are online. There is no Save button, so a "lost" notebook is almost always a sync problem, not a save problem. If a note is missing on your phone, check that the notebook finished syncing on the computer where you wrote it before assuming the note is gone.

Storage comes with the account, not the app. A free Microsoft account includes 5 GB of cloud storage shared across OneDrive files, Outlook.com attachments, and Microsoft 365 apps, according to Microsoft's storage FAQs. Microsoft 365 Personal adds 1 TB of OneDrive storage, and new Microsoft 365 Family and Premium subscribers get 2 TB of shared storage under the terms Microsoft published in October 2026. Plain text notes are tiny, so storage only becomes a real limit when notebooks fill up with large photos, videos, and file attachments.

When sync stalls, look for the warning on the notebook and resolve it before you keep writing, because unsynced changes are the ones that go missing. In the current OneNote app, right-click the notebook and choose Sync Now, then check the View tab for Misplaced Sections, where pages that could not sync are parked. Move those pages into a real section and let them sync. Never uninstall an old OneNote app before confirming every notebook opens correctly in the new one, because uninstalling deletes local data that never synced.

Which OneNote app should I use on Windows?

Use OneNote on Windows, the current app with a File menu at the top left, because it is the only Windows version Microsoft still supports. The older OneNote for Windows 10 app reached end of support on October 14, 2025, and switched to read-only mode: you can open and view old notes in it, but you cannot create, edit, or sync anything new. Microsoft's own check is simple: if your OneNote has a File menu, you have the current app, and if it does not, you are on the retired one.

Migration is mostly a sign-in, not a project: open the current app, sign in with the same Microsoft account, and your cloud notebooks appear. The only notes at risk are ones that never synced in the old app, so sync the old app fully first, then verify each notebook in the new app before uninstalling the old one. New Windows 11 devices no longer include the retired app at all, which is one less decision for new users.

What can Copilot do in OneNote, and who gets it?

Copilot in OneNote can summarize a page or section, turn meeting notes into a to-do list, rewrite notes for clarity, draft plans and outlines, and answer questions about your notes in a chat pane. You open it from the Copilot button on the Home tab. It is a writing and thinking helper that reads the notes you point it at; it does not replace the notebook, and its output still needs checking before you share it.

Copilot is not included with a free Microsoft account. Microsoft's Copilot in OneNote help states it is available to customers with a Microsoft 365 Copilot work license in OneNote for Microsoft 365, and to those with an eligible Microsoft 365 subscription in OneNote for Windows only. Personal and Family subscribers use a monthly allowance of AI credits shared across Microsoft 365 apps, and when the credits run out, Copilot pauses until the next month. If the Copilot button is missing or greyed out, the usual cause is the account, not the app: check the subscription before reinstalling anything.

Start with two prompts that show Copilot's value fast: "Summarize this section in five bullet points" and "Make a to-do list from my meeting notes on this page." Both work on notes you already wrote, which is the point: Copilot is most useful on a notebook that already has content, and least useful on an empty one. For a first month with OneNote, the notebook itself matters more than the AI add-on, so learn the structure first and add Copilot only when summaries and task lists would save real time.

OneNote vs Notion: which should a beginner pick?

OneNote vs Notion comes down to one question: do you want a free-form page that behaves like paper, or a structured workspace built from databases and blocks? OneNote wins for quick capture, handwriting, and mixed media on a single page. Notion wins for structured databases, published pages, and team wikis where every item has properties. A student taking lecture notes usually wants OneNote; a team tracking projects in a shared database usually wants Notion.

Many people end up using both, and that is fine: capture in OneNote, publish or track in Notion. Our Notion beginner guide covers the workspace side if you go that route, and our Obsidian beginner guide covers the local-first alternative, where notes live as plain files on your own computer instead of in a cloud account. The wrong choice is not fatal in any of these apps, because notes can be exported and moved, but switching costs a weekend, so pick the one that matches how you actually take notes.

How do I share a notebook and work with other people?

To share a notebook, open it from OneDrive or SharePoint and invite people by email, choosing whether they can view or edit. Sharing works at the notebook level, not the page level, so a shared notebook means shared access to every section inside it. For a class project or a team, that is usually what you want; for private notes mixed with shared ones, keep two notebooks instead of one.

Shared notebooks show who edited what, and changes sync to everyone, which makes OneNote a decent meeting-notes tool for small teams. The failure mode is permission sprawl: a notebook shared with "everyone with the link" stops being a team notebook and becomes a public one. Share with named people, check the list once a quarter, and remove people who no longer need access. For meeting notes specifically, agree on one rule before the first shared meeting: the note-taker owns the page, and everyone else adds comments rather than rewriting the original notes.

What is the first-week OneNote routine that keeps notebooks tidy?

The first-week routine is one notebook, three sections, and a ten-minute Friday tidy. Start with a single notebook for your main area, add an Inbox section for quick captures, a Projects section for real work, and an Archive section for anything finished. Every note you take in week one goes into Inbox or Projects, and nothing else. That constraint is the whole system: it prevents the "one giant notebook" problem before it starts.

After week one, the only new habit is the Friday tidy: file the Inbox, tag the actions, and archive what is done. If a notebook still feels messy after a month, the cause is almost always too few sections, not too many: split the busiest section and the mess resolves itself. OneNote rewards small, regular maintenance far more than grand reorganizations, which is why the weekly ten minutes matters more than any feature in this guide.

Frequently Asked Questions

Is Microsoft OneNote free?

Yes. OneNote itself is free with a Microsoft account on Windows, Mac, the web, iOS, and Android. A paid Microsoft 365 subscription adds storage and Copilot, but the core notebook, sections, pages, tags, and search work without one.

Do I need Microsoft 365 to use OneNote?

No. A free Microsoft account is enough to create notebooks, take notes, and sync across devices. Microsoft 365 matters only for extra OneDrive storage and for Copilot inside OneNote, which needs a qualifying subscription or license.

What happened to OneNote for Windows 10?

OneNote for Windows 10 reached end of support on October 14, 2025, and became read-only. You can still view old notes in it, but to create, edit, or sync notes you must use the current OneNote on Windows app, which you can confirm by the File menu at the top left.

Can I use OneNote offline?

Yes. You can write and edit notes offline, and OneNote syncs the changes to OneDrive when you reconnect. The catch is unsynced changes: if a notebook shows a sync warning, resolve it before switching devices, or the newest edits may not appear elsewhere.

Is OneNote better than Notion for beginners?

For free-form note-taking, yes: OneNote's click-anywhere pages, handwriting, and automatic saving are easier on day one. For structured databases, trackers, and team wikis, Notion is the stronger tool. Many beginners start in OneNote and move structured work to Notion later, which is a reasonable path, not a mistake.
