The iCalendar ICS file type is a universal format for storing and displaying calendar files. ICS files can be opened by several calendar programs, including Microsoft Outlook 2013. While you can import ICS files manually into Outlook using the “open and export” menu, it’s easier to automatically associate the file format with Outlook. With this association, you can automatically add the ICS files to Outlook when you open the file. You’ll save a lot of time if you receive regular event or meeting invitations in this format.
