Receiving reminders for calendars that are not mine

I have a Google account connected to my job. I can view other coworkers’ shared calendars, as a result. I have opted NOT to view their calendars (their calendars are unchecked). There is one coworker whose events eM Client keeps sending me reminder about. How can I disable notifications for this calendar?

In eM Client, go the Calendar section.

Right-click on the shared calendar and select Properties.

Untick Show reminders.

Thanks very much! I think my issue related to the calendars being checked in the actual Google Calendar app. I unchecked them there and hopefully my issue will resolve.
