The Mark All As Read tool makes it easy to mark all of your unread calendar events as read (with the click of a button). This is useful for times when you have a lot of unread events and manually marking each one as read would be tedious.
OVERVIEW
Open your Calendar.
Near the top-right corner, click the View All Unread icon.
Click on Mark All as Read. MyCase will then mark all of your Unread Events as read.
