Subscribing means that you see all bookings in the Planner’s Calendar in your private calendar (Outlook, iOS, Google…).
You cannot add or move bookings in your private calendar to update the calendar in the Planner.
Do this:
- Click on your username to access your account settings.
- Copy the link under ICL.
- Paste it into your calendar service. Look for Add Subscribed Calendar or Subscribe to Calendar. It depends on which service you use.
