Can't turn off email alerts for events in Yosemite After I've upgraded to Yosemite, I've started to receive email alerts about upcoming events from my Calendar. This is a typical email

My OSX Calendar is connected to my Google Account. And takes events info from Google Calendar.

I have disabled all notifications for OSX Calendar. http://take.ms/ZVQus

But I still receive email notifications about upcoming events. Since I also receive them from Google Calendar, I get all notifications twice.

How to disable them?
This worked for me:

Open Calendar on your Mac.

In the left column list of calendars, right click (or command-I) on the calendar in question and "Get Info"

Check the box labeled "Ignore alerts"

Hit "OK"
