The short version

  • Each has a real cost: Google Calendar no AI-driven scheduling assistance or automatic meeting time optimization; Microsoft OneNote notes live in a proprietary notebook format on OneDrive or SharePoint and the only exports are a OneNote file, a PDF or a Word document, produced section by section, so a large notebook is effectively unmovable to any other tool.
  • They diverge on capability: Google Calendar covers Event scheduling, Microsoft OneNote covers Free-form page canvas.
  • Prices and features above were last checked on 30 August 2026.

  • Lecture or meeting notes where a recording needs to line up with what you were typing at the time.not Google Calendar
  • A team already inside Microsoft 365 that needs a shared notebook without buying anything or seeking approval.not Google Calendar

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Google Calendar

  • No AI-driven scheduling assistance or automatic meeting time optimization
  • Lacks built-in appointment booking pages or payment integrations for scheduling
  • Limited mobile support for shared calendars and unreliable push notifications on phones
  • No native task management or project tracking features within the calendar interface
  • Limited offline functionality on the web (read-only mode only)
  • Strict usage limits (maximum 60 calendars, 750 shares per time period)

Microsoft OneNote

  • Notes live in a proprietary notebook format on OneDrive or SharePoint and the only exports are a OneNote file, a PDF or a Word document, produced section by section, so a large notebook is effectively unmovable to any other tool.
  • Personal notebooks consume OneDrive quota, which is 5 GB on a free Microsoft account, so a notebook full of scans, images and recordings quietly exhausts the whole account including the space Outlook needs for mail.
  • Sync happens at section level and conflicts are resolved by placing both versions on the page, so simultaneous edits to a large or media-heavy section produce duplicated content that somebody has to merge by hand.
  • Search behaves differently across clients, so what the Windows desktop app finds inside handwriting, images and attachments is not necessarily what the browser or mobile version finds, and the same query gives different answers on different devices.
  • There is no relational structure, no database and no properties, so anything that needs a table of records with fields has to be maintained by hand or moved elsewhere, and OneNote's own tables cannot be queried or filtered.

Answered from the vendors’ own pages

Google Calendar: Can I use Google Calendar offline?

Yes. On the web, Google Calendar works in read-only mode offline for cached events. On iOS and Android, the Google Calendar app automatically caches recent events and lets you create, edit, and respond to events offline. Changes sync automatically when you reconnect to the internet.

Source
Microsoft OneNote: Is OneNote really free?

Yes. The application is free with a Microsoft account, with no time limit and no feature gate. What you may end up paying for is the OneDrive storage the notebooks consume.

Google Calendar: Can I export my calendar data?

Yes. Google Calendar exports as ICS files through Settings > Import & export > Export. ICS files are readable by Outlook, Apple Calendar, Thunderbird, and most other calendar applications.

Source
Microsoft OneNote: Can I keep notebooks off Microsoft's cloud?

The Windows desktop app can keep local notebooks, but they will not sync to other devices and any shared access requires OneDrive or SharePoint.

Google Calendar: Does Google Calendar integrate with video conferencing?

Yes. Google Calendar integrates natively with Google Meet and Zoom. When you create an event, you can add a video conference link directly. Other platforms like Webex and GoTo Meeting can be integrated via Zapier or third-party automation.

Source
Microsoft OneNote: How do I get my notes out?

Section by section as a OneNote file, a PDF or a Word document. A OneNote package preserves a whole notebook but only for another copy of OneNote. Third-party converters exist and the page layout usually does not survive them.

Google Calendar: Can I share my calendar with teams?

Yes. You can share individual calendars with specific people or make them publicly viewable. However, accessing shared calendars on mobile devices has limitations, and push notifications for shared calendars may not work reliably on phones.

Source
Microsoft OneNote: Which version should I install?

Microsoft consolidated onto a single OneNote application on Windows after retiring the Store version, so install the one distributed with Microsoft 365 rather than looking for an alternative.

Google Calendar: Does Google Calendar work with Outlook?

No direct integration. You can manually import/export using ICS files or use third-party tools like Zapier to sync events. This is different from Outlook, which integrates seamlessly within Microsoft 365.

Source
Google Calendar: Is there a cost to use Google Calendar?

Google Calendar is free for personal use. Google Workspace plans (which include Calendar) start at $7 per user per month for business use.
