Calendar sync from Outlook to Google

A script made for my personal needs while ago. For some reason, the outlook calendar doesn't sync with google calendar that well and I ended up missing some meetings because of that.

I needed a solution so I made this script that runs on a VPS somewhere on hourly basis using cron.

Feel free to grab this and refactor it to your needs.

Requirements

• Python 3.12
• Pip
• Virtualenv
• Outlook account
  • A calendar share link from outlook
• Google account
• Google API credentials

  • You don't need to have a billing account for this. Just create a project in google cloud console and enable the calendar API.

  • Go to your console (create a project) and navigate to APIs & Services. Click Create Credentials

    

  • Use a service account for this

  • 

  • Create the account. Take note of the email address. Copy it and save it somewhere

  • 

  • You don't need to give the account any permissions

  • Save the credentials as cr.json inside the project folder root

  • Navigate to calendar.google.com and create a new calendar. Share the new calendar with the service account email.

  •
