How to export Google Calendar to Outlook?

Moving my scheduling from Google Calendar to Outlook. Years of events, some recurring, plus a shared team calendar.

Do I want a one time export or is there a way to keep Outlook fed from Google while I transition?

Both exist and they suit different calendars of yours, so use each where it fits.

One time export for your own calendar: in Google Calendar on the web go to Settings, Import and export, Export. You get a zip holding one .ics per calendar. In Outlook do File, Open and Export, Import/Export, Import an iCalendar (.ics) file and pick Import rather than Open as New so the events merge into your main Outlook calendar. Recurring events carry over with their rules intact.

Live feed for the shared team calendar: in Google open that calendar's settings, scroll to Integrate calendar and copy the Secret address in iCal format. In Outlook go to Calendar, Add Calendar, From Internet and paste it. Outlook refreshes the feed periodically, so the team calendar keeps updating while everyone migrates. It is read only in Outlook, which is what you want during a transition.

Once the migration finishes, delete the Internet calendar subscription and export the shared calendar the one time way too. Leaving secret addresses in circulation is a quiet security hole since anyone with the URL reads the calendar without signing in.

Imported my personal calendar, all the recurring meetings came through with correct rules. Team calendar is on the live feed until the department finishes moving.
