Work offline in Microsoft OneNote for iPad or iPhone

Microsoft OneNote automatically syncs your changes as you work. This happens with your own notebooks that you use across different devices and computers, as well as with notebooks that you've shared with other authors. If at any time you lose your Internet connection or turn off your device or computer, any pending changes that you've made will be automatically synced as soon as you're back online.

Though syncing OneNote manually on your iPhone or iPad is not required, you can choose to always sync all pages with attachments (including images) for offline use.
