Copy the all-series or one-series URL and add it as a calendar subscription. The feed serves the latest stored schedule whenever your calendar app checks it; the app controls refresh timing.
ICS events use absolute start times, so the same green flag appears correctly when your device timezone changes. Set reminders inside your calendar app after importing or subscribing.
Calendar app setup
On the desktop site, open Other calendars, choose From URL, paste the copied subscription URL and add the calendar. For a snapshot, use Import and select the downloaded .ics file.
On a Mac, choose File → New Calendar Subscription and paste the URL. On iPhone or iPad, add a subscribed calendar in Calendar account settings, or open a downloaded .ics file.
Choose Add calendar, then subscribe from the web and paste the URL. Importing the downloaded .ics creates a snapshot instead; the wording varies slightly between Outlook versions.
Quick answers
