Why do I have to sign in?

OneNote for Mac syncs your notes with OneDrive, so your notes are available on all your devices, and they’re always up-to-date. To access your notebooks, sign in with a Microsoft account or the account assigned to you by your work or school.

A Microsoft account is an email address used to sign in to Microsoft services. You already have an account if you use any of these services:

  • Outlook.com

  • OneDrive

  • Xbox LIVE

  • MSN

  • Messenger

  • Microsoft 365 Family subscription
