Events show upin agenda but not on calendar

I’m a new user just moving from Outlook, after 15 years. Like most of the features, but I’d really like to be able to view a month or a week of events at one time. The events all appear in the Agenda pane with tags, etc, but they don’t show up in the calendar. I’m sure its an unchecked box, but I can’t find it.
I also keep getting an error message “Password required for CALDAV” I keep my calendar on my desktop with Outlook and my iPhones syncing throuh iCloud.
