To add your Google Calendar to Outlook without making it public, follow these steps:
* Log in to your Google Calendar account and go to the “My calendars” section.
* Select the calendar you want to import and click on the settings gear icon.
* Choose “Settings and sharing” and ensure that the calendar is set to “Public” or “Visible to everyone”.
* Import the calendar into Outlook by selecting “Add this calendar to my Outlook calendar”.
* Save the settings to ensure your calendar is added without making it public.
This way, you can keep your calendar private while using it in Outlook.


My best guess is it’s because the instructions are about how to use your calendar in Outlook without making it public, but one of the steps is to make your calendar public.
Other than that, not sure.
