It’s pretty straight forward.
1. Log in to your Live/Hotmail account and select the Send People a view-only link to your calendar. Select the ICS: Import into another calendar application, it will bring up a window with an ICS link, i.e. webcal://cid….calendar.ics
Copy this link
2. Log in to your Google Calendar account and select add, under other calendars, select Add by URL, and paste the ics link copied.
Click Add Calendar
Wait a few minutes and you should see the calendar show up.
If you go into the settings under Other calendars, you will see the webcal link, click on that link and change the calendar name, to whatever you would like it to be.
Close the window and now the name of the calendar should show up.
