Windows 8.1 Calendar support

Is it possible to show/sync with Windows 8.1 Calendar app?

Ideally, I would like to see the same events in Calendar app and in emClient and sync those to Google Calendar. Can emClient do any of these?

Hi, unfortunately this is not possible directly. You have to set same account with Calendar support for Windows Calendar and eM Client, then they will synchronize their calendars over internet.
