Sometimes, I want to combine two Outlook calendars. You’ll need to hover over each item to check the details. While this is a convenient feature, Outlook won’t inform you of overlapping events. You’ll probably want to hover over calendar events to get details such as End times and Reminder notices. The colors correspond to the ones you set for each calendar.
