I've been trying to figure this out but so far can't see a way to do it... My setup involves me having my personal mail and calendar on mail, my work email/calendar is handled in Outlook. The thing here is I also share my work calendar with calendar app (So i can see all my events on mobile, or a non work machine). The annoying thing is I now get alerts from Office notification plus alerts from notification center for meetings. I could turn notifications off for calendars, but I would still like to be alerted to events in my personal calendars... Does anyone know if it is possible to turn off alters/banners for a specific calendar?
